YSN Imports Recalls Refillable Propane Cylinders Due to Fire, Explosion Hazards

What was recalled

If you have been using portable propane cylinders for your outdoor grill, camping stove, or patio heater recently, it is important to pause and check your equipment. The U.S. Consumer Product Safety Commission (CPSC) has issued a recall involving specific refillable propane cylinders manufactured by YSN Imports. This action was taken because these products present a serious safety risk that could lead to dangerous situations if not addressed immediately. The recall, which was officially announced on July 13, 2017, targets three distinct brands of refillable fuel containers: Flame King, Little Kamper, and U-Haul. These items were designed to be refilled and reused with various outdoor appliances, making them a common sight in many households that enjoy camping or outdoor cooking.

The specific products affected by this recall are defined by their brand, size, color, and serial number range. It is crucial to note that not every cylinder made by these brands is included; only those falling within the exact serial number ranges identified in the official report are subject to the recall. For the Flame King brand, two sizes are involved: the 14.1-ounce blue cylinders with serial numbers ranging from 000001 through 004700, and the 16.4-ounce green cylinders with serial numbers from 000001 through 020800. Similarly, the Little Kamper brand includes the 16-ounce green cylinders, also covering serial numbers from 000001 through 020800. The U-Haul brand is represented by two entries as well: the 1-pound blue cylinders with serial numbers from 000001 through 004700, and the 1-pound green cylinders with serial numbers from 000001 through 020800. The brand logo and size information are printed on the front of each cylinder, while the critical serial number is located on the foot ring at the base.

While the provided recall facts do not specify the exact retail locations or the precise dates during which these units were sold, they confirm that these specific models were distributed widely enough to warrant a national safety alert. Consumers who purchased these items, whether new or potentially second-hand, need to verify their serial numbers against the ranges listed above. The inclusion of well-known brands like U-Haul and Flame King suggests that these cylinders were likely available through major retail chains, hardware stores, and online marketplaces. Because the hazard involves a potential leak in the connecting valve, identifying whether your specific unit falls within the recalled serial number range is the first critical step in ensuring your safety.

If you own any of these cylinders, do not assume they are safe simply because they have been working fine up to this point. The defect involves the connecting valve starting to unscrew from the cylinder, a failure mode that can occur even if the product appears intact on the outside. Therefore, checking the serial number is not just a formality; it is a necessary safety check. If your cylinder’s serial number falls within the specified ranges for any of the listed brands and sizes, it is part of this recall and should be handled with caution until you can contact YSN Imports for a refund or replacement.

The hazard, explained

At the heart of this recall is a seemingly simple mechanical failure that can have serious consequences. The recalled refillable propane cylinders from YSN Imports—sold under the Flame King, Little Kamper, and U-Haul brands—contain a critical defect in their connecting valves. Specifically, the valve that attaches the cylinder to your outdoor appliance (like a grill or heater) is prone to unscrewing itself from the cylinder body. While these tanks are designed to hold pressurized gas safely, this particular failure mode transforms the tank from a stable fuel source into an uncontrolled release mechanism.

To understand why this is dangerous, it helps to look at what happens inside the tank. Propane is stored under significant pressure. When the connecting valve begins to unscrew or detach, that pressure has nowhere to go but out. This results in a rapid, high-volume leak of propane gas. Propane is heavier than air, meaning it does not simply dissipate into the sky like natural gas might; instead, it sinks and pools along the ground, sidewalks, or in low-lying areas near your home. This pooling creates a large, invisible cloud of fuel that can linger long after the initial leak.

The primary danger here is ignition. Propane is highly flammable. If this leaking gas encounters any source of ignition—whether it’s the pilot light on your grill, the spark from an electrical outlet, a lit cigarette, or even static electricity—it can ignite instantly. This can lead to a flash fire, where flames erupt rapidly around the source of the leak. In more severe cases, if the gas cloud builds up in an enclosed or semi-enclosed space, such as a patio, garage, or under a deck, the resulting explosion can be catastrophic, causing significant property damage and structural harm.

While the Consumer Product Safety Commission (CPSC) reports that YSN Imports has received two specific incidents where the valve started to unscrew, they note that no injuries have been reported so far. This is fortunate, but it does not mean the risk is low. The potential for injury remains high because a leak of this nature can escalate quickly. A small leak might be manageable if you catch it early and move away from any ignition sources, but a complete detachment of the valve can lead to an immediate and uncontrolled fireball. Therefore, treating every detected defect as an immediate emergency is the only safe approach.

It is also important to note that this hazard is not just about the gas itself, but about the loss of control over the fuel source. When a cylinder is properly attached, you can turn the appliance off and regulate the flow. When the valve unscrews, you lose that regulation entirely. The tank continues to vent its contents until it is empty or until something ignites it. This unpredictability is what makes the defect so hazardous in domestic settings where people may be cooking, gathering, or relaxing nearby.

Who is most at risk

The individuals most immediately vulnerable to the hazards presented by these recalled YSN Imports propane cylinders are those who actively utilize them for outdoor recreational activities. Because these specific models—branded as Flame King, Little Kamper, and U-Haul—are designed as refillable units for portable appliances, the primary group at risk comprises campers, tailgaters, and homeowners using outdoor grills or heaters. These consumers often operate their equipment in environments where they may be less vigilant about routine safety checks compared to indoor gas usage. The nature of these cylinders is such that they are frequently handled, transported, and connected to various appliances, increasing the likelihood of mechanical stress on the connecting valve. For anyone who owns one of the serial number ranges listed above, the risk is not theoretical; it is present every time the cylinder is filled or attached to a stove.

A critical aspect of this vulnerability lies in the specific failure mode identified in the incident reports: the connecting valve starting to unscrew from the cylinder. This mechanical failure poses a disproportionate danger to individuals who may be unaware of the defect until it is too late. Propane is heavier than air and highly flammable. If the valve begins to separate, gas can escape rapidly into the immediate vicinity. For users operating these cylinders near open flames, such as on a campfire or a lit grill, this leak can ignite almost instantaneously. The risk is particularly acute for families with children nearby. While children may not be the ones handling the heavy green or blue cylinders, they are often the bystanders at picnic tables or campsites. A sudden explosion or flash fire caused by a leaking valve can cause severe burns and trauma to anyone in the immediate blast radius, regardless of their age.

Furthermore, elderly users or those with limited mobility may face heightened risks due to the physical handling required for these refillable tanks. These cylinders are not disposable; they require careful screwing onto regulators and unscrewing for refilling. If a user has diminished grip strength or dexterity, they might inadvertently overtighten or under-tighten connections, potentially exacerbating wear on the valve threads over time. Although the recall notes that no injuries have been reported to date, the potential for harm is significant because propane leaks can be invisible and odorless until an additive is present, and even then, detection may be delayed if the user is distracted by cooking or socializing. The combination of a mechanical failure in a high-pressure fuel source and the casual environment of outdoor recreation creates a perfect storm for accidents. Therefore, anyone who has purchased these items between the relevant dates and owns a cylinder within the specified serial number ranges should consider themselves part of the at-risk group until they have verified their unit’s status or completed the recall remedy. Ignoring the warning is not an option, as the consequence of a valve failure is not merely an inconvenience, but a serious safety emergency.

How to tell if you have the recalled item

If you own any refillable propane cylinders for your outdoor grill, heater, or camp stove, it is crucial to verify whether yours are part of this specific recall before using them again. The recall issued by YSN Imports on July 13, 2017, targets three distinct brands: Flame King, Little Kamper, and U-Haul. Because these products look very similar to safe, non-recalled cylinders at a glance, you cannot rely on size or color alone. You must check the specific combination of brand, capacity, color, and serial number range printed on the unit.

The most reliable way to identify a recalled cylinder is by looking at two specific areas on the metal body. First, look at the front face of the cylinder where the brand logo and size are clearly printed. Second, turn the cylinder over or look at the bottom foot ring. The serial number is stamped or printed directly onto this foot ring. This is your definitive proof point. If the serial number falls within the ranges listed below for a recalled brand and color combination, you must stop using the item immediately.

Please compare your cylinder against the following specific criteria. A recall only applies if the brand, size, color, AND serial number all match:

• Flame King 14.1 oz. cylinders: These are blue in color. The recalled serial numbers range from 000001 through 004700.
• Flame King 16.4 oz. cylinders: These are green in color. The recalled serial numbers range from 000001 through 020800.
• Little Kamper 16 oz. cylinders: These are green in color. The recalled serial numbers range from 000001 through 020800.
• U-Haul 1 lb. cylinders: There are two variations here. Blue U-Haul cylinders with serial numbers 000001 through 004700 are recalled. Green U-Haul cylinders with serial numbers 000001 through 020800 are also recalled.

If you cannot read the serial number because it is worn off, dirty, or obscured by rust, do not attempt to use the cylinder. The inability to verify that your unit falls outside the dangerous range means you should treat it as potentially unsafe. Contact YSN Imports for assistance in identifying your specific model if needed. Do not rely on general descriptions; the serial number is the key identifier that determines whether your propane cylinder is safe to keep or must be returned.

What to do — step by step

Your refund, repair, or replacement options

If you have identified one of the recalled propane cylinders in your possession, the most important thing to understand right now is that YSN Imports has committed to making this situation right for you. The remedy offered is straightforward and consumer-friendly: you are entitled to either a full refund or a replacement propane cylinder. This choice puts the power back in your hands, allowing you to decide what works best for your current needs and budget. However, before you reach out, it is helpful to understand why this specific remedy was chosen and how the process generally works with these types of safety recalls.

The reason a refund or replacement is the standard remedy here lies in the nature of the defect. Because the connecting valve on these cylinders can unscrew from the base, it represents a fundamental structural failure that cannot be safely patched or repaired by the average consumer. Attempting to fix a gas leak or a loose valve on a pressurized container at home is extremely dangerous and not recommended by safety experts. Therefore, the manufacturer is stepping in to remove the hazardous unit entirely from your home and provide you with a safe alternative. This ensures that you are no longer exposed to the fire and explosion risks associated with the leaking gas.

To initiate this process, you will need to contact YSN Imports directly. They have set up specific channels for this recall to ensure your request is processed correctly. You can reach them by phone at their toll-free number, 855-215-4970. Their customer service team is available from 8 a.m. to 5 p.m. Eastern Time, Monday through Friday. This window of time allows you to plan your call during standard business hours if that suits your schedule better. Alternatively, if you prefer written communication or need to send documentation, you can email them at flameking7685@stericycle.com. Email can be a useful option if you want to keep a paper trail of your request or if you have multiple units to report.

For those who prefer to navigate the process online, YSN Imports has also established a dedicated section on their website. You can visit www.flameking.com and look for the "Recall Information" link. This page likely contains forms, additional instructions, or updates regarding the status of the recall. Using the online portal can be efficient if you are comfortable with digital interfaces and want to review information at your own pace before submitting your claim.

When you contact them, whether by phone, email, or online, be prepared to provide details about your specific unit. This includes the brand name (Flame King, Little Kamper, or U-Haul), the size of the cylinder, its color, and most importantly, the serial number printed on the foot ring. Having this information ready will help the customer service representative verify that your item is part of this specific recall batch and expedite your refund or replacement shipment. Remember, the goal is to ensure you have a safe, functional propane cylinder for your outdoor appliances without any financial penalty for their manufacturing oversight.

What can happen if you ignore it

When a product recall involves fire and explosion hazards, the stakes are inherently high because propane is a highly volatile fuel source. Ignoring this recall means continuing to use equipment that has been identified as structurally compromised in a critical area: the connecting valve. The recall notice indicates that YSN Imports has already received two reports of the connecting valve starting to unscrew from the cylinder. While no injuries have been reported to date, the mere fact that these valves are failing under normal operating conditions suggests that a catastrophic failure is not a matter of "if," but rather "when." Choosing to ignore this warning puts you at risk of turning a routine outdoor cooking or heating session into a dangerous emergency.

The primary danger lies in the nature of propane gas itself. These recalled cylinders are designed to hold pressurized fuel, and when the connection point fails, that pressure is released instantly. Propane is heavier than air, meaning that if it leaks from an unscrewing valve or a faulty seal, it does not simply dissipate into the atmosphere like steam. Instead, it sinks and pools around the base of the appliance, in low-lying areas, or within enclosed spaces like the undercarriage of a grill or inside a tent. If you continue to use these cylinders, you are essentially creating invisible gas clouds around your equipment. A single spark—whether from an igniter button, static electricity, or even a nearby pilot light—can ignite this pooled gas.

The consequences of such an ignition can range from a dangerous flash fire to a more severe explosion. A flash fire can cause severe burns to anyone standing nearby, including you and your family members who may be assisting with cooking or setup. In worse-case scenarios, the pressure release combined with ignition can lead to projectile hazards, where parts of the cylinder or the connected appliance are propelled outward with significant force. This risk is amplified if the leak goes unnoticed for a period of time, allowing gas concentrations to build up to explosive levels before any flame source is introduced.

Furthermore, ignoring the recall means you are relying on a defective component that was not manufactured to safety standards. The fact that the valve can unscrew under use indicates a fundamental flaw in the threading or locking mechanism. By continuing to use these units, you are gambling with your physical safety and potentially the safety of others around you. There is no upside to this risk; the convenience of keeping an old cylinder on hand does not outweigh the potential for serious injury, property damage, or even loss of life. The two reported incidents serve as a clear warning sign that the failure mode is real and active. It is far safer to accept the inconvenience of swapping out the cylinder than to face the potential aftermath of a propane-related accident.

Staying safe: broader tips

While specific product recalls address immediate defects in manufactured goods, long-term safety with propane equipment relies on consistent, proactive habits and a solid understanding of how these fuels behave. Propane is an excellent energy source for outdoor cooking and camping because it burns cleanly and provides reliable heat. However, because it is heavier than air and highly flammable, it requires a level of respect and routine maintenance that goes beyond simply following the instructions on the canister. By adopting a few broader safety practices, you can significantly reduce the risk of accidents in your home, garage, or campsite.

First and foremost, always inspect your equipment before every use. Over time, rubber gaskets, O-rings, and seals can dry out, crack, or wear down due to exposure to sunlight, extreme temperatures, or general friction. A small hairline fracture in a valve seal might not cause an immediate leak during a quick check, but it can release gas under pressure when you connect the cylinder to your appliance. Take a moment to look for visible damage, corrosion, or rust on the cylinder body and valves. If you notice any signs of wear, do not attempt to patch or repair the component yourself; replace the entire assembly or consult a professional. Additionally, ensure that all connections are tight and secure before igniting your appliance. A loose connection is one of the most common causes of gas leaks in outdoor settings.

Ventilation is another critical factor that is often overlooked until it is too late. Propane displaces oxygen, and in confined spaces such as enclosed trailers, tents, or garages, even a minor leak can lead to dangerous accumulation levels. Never use propane appliances indoors unless they are specifically designed for indoor use with proper venting systems. When camping or using equipment outdoors, always position your cylinders upright on a stable, flat surface away from open flames, sparks, or high-heat sources. This prevents the pressure relief valve from activating unintentionally and ensures that any potential leak disperses quickly into the atmosphere rather than pooling near the ground where it can ignite.

Finally, stay informed about product safety beyond just your current purchases. Regularly check the Consumer Product Safety Commission (CPSC) website and sign up for email alerts to receive immediate notifications about recalls affecting products in your home. Many dangerous defects are identified only after widespread use, so being proactive is your best defense. Store propane cylinders in a cool, dry, and well-ventilated area when not in use, keeping them away from direct sunlight and heat sources that could raise internal pressure. By combining careful inspection, proper ventilation, and ongoing awareness of safety recalls, you create a robust layer of protection for yourself and your family.
