Diving Inflation Valves Recalled Due to Risk of Hypothermia; Manufactured by SI TECH

What was recalled

The U.S. Consumer Product Safety Commission (CPSC) has issued a voluntary recall concerning specific Shell Inflation Valves manufactured by SI Tech. These components are critical safety devices used in diving dry suits, which are essential gear for recreational and technical divers who operate in cold water environments. The recalled items are the Shell Inflation Valves equipped with International (Int'l) Nipples. It is important to note that these valves were not only sold as part of complete diving dry suit packages but were also available for purchase separately, meaning they may be installed on suits from various manufacturers or used as replacements in older gear.

The primary scope of this recall focuses on specific model numbers and their associated batch codes. The affected products include Model Number 25210 with the following variants: JD1, JE2, JE5, JE6, JF6, JG2, JK6, JK9, JKA, JL1, JL3, KA7, KB8, KG2, KH3, KH4, KK7, KL3, LC1, LC2, LC4, LC7, LC9, LD2, LD6, LD7, and LD8. Additionally, the recall covers Model Number 25215 with variants JG1, KA9, and LC5. The specific batch code for each unit is stamped directly on the inside of the valve, which serves as the definitive identifier for determining whether a particular unit falls within the scope of this safety action.

While the official recall announcement does not specify the exact number of units involved in this recall, it is important to understand the context of these products. SI Tech is a well-known manufacturer of diving equipment, and their inflation valves are widely distributed globally. These components were sold both domestically within the United States and internationally. Because they are often sold separately, divers who purchased them from third-party retailers, online dive shops, or direct from manufacturers other than SI Tech may still possess a recalled item. The recall date for this action was April 14, 2022, indicating that these products have been on the market for some time and may be in active use by divers today.

To confirm if you own one of these recalled valves, you must inspect the physical product closely. Look for the model number and batch code stamped on the interior surface of the valve mechanism. If your valve matches any of the model numbers listed above (25210 or 25215 with the specified variants), it is part of this recall. For assistance in identifying the batch code or verifying the specifics of your unit, SI Tech provides detailed instructions on their official website at www.sitech.se. If you are unsure whether your specific configuration is included, it is safer to assume it might be and proceed with the verification steps outlined by the manufacturer.

The hazard, explained

To understand why this recall is so critical, it helps to look at the specific mechanical failure that SI Tech has identified in its Shell Inflation Valves. These valves are not merely decorative; they are the primary mechanism that allows a diver to maintain their buoyancy and, crucially, their warmth while submerged. The valve’s internal component is designed to inflate the dry suit with air as you descend into deeper water. This inflation counteracts the increasing water pressure, preventing the suit from collapsing around your body. However, in the affected units, this internal part can malfunction during use. When this failure occurs, the valve stops inflating the suit effectively, leading to an immediate loss of inflation.

The danger here is twofold, with thermal protection being the most severe consequence. A dry suit relies on a layer of trapped air to insulate the diver from the cold water outside. This air acts as a barrier, keeping your body heat in and the freezing environment out. When the inflation valve malfunctions and fails to maintain this pressure, the suit begins to deflate or "limp." Without that pressurized air cushion, the material of the suit presses tightly against your skin. In cold water, which conducts heat away from the body up to 25 times faster than air, this direct contact is dangerous. It strips away your thermal protection almost instantly.

This rapid loss of insulation creates a high risk of hypothermia. Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce it, causing your core temperature to drop below normal. Even in relatively mild water temperatures, the sudden onset of cold shock and subsequent heat loss can impair a diver’s judgment, dexterity, and consciousness. While SI Tech has received three reports of this valve malfunctioning, resulting in the loss of inflation, no injuries have been reported as of the recall date. This absence of injury is fortunate but does not diminish the severity of the potential hazard; it simply means that in these specific instances, divers may have been lucky to surface safely or had other mitigating factors.

The mechanism of failure is particularly insidious because it can happen without warning while you are underwater. You might press the valve to adjust your buoyancy, expecting it to function normally, only to find that the suit is no longer holding air. This leaves you with a suit that offers little to no thermal protection against the surrounding water. For recreational and technical divers alike, relying on this equipment for safety means that any failure in its core inflation system is a significant threat to personal well-being. The risk is not just about discomfort; it is about the physiological stress of cold water immersion, which can lead to serious health complications if not addressed immediately.

Who is most at risk

The primary group facing potential danger from this recall consists of recreational and technical divers who utilize dry suits equipped with the specific SI Tech Shell Inflation Valves. Unlike standard wet suits that allow water to enter and rely on a thin layer for insulation, dry suits create a waterproof barrier, trapping air or gas inside to provide thermal protection against cold water environments. The recalled inflation valves serve a critical dual function: they allow the diver to equalize air pressure while descending to prevent ear and suit squeeze, and they maintain the necessary air volume that acts as an insulating layer between the diver’s body and the freezing water. Therefore, anyone who owns or rents dry suits compatible with these specific valve models is potentially at risk if they continue to use the defective components.

The vulnerability of the consumer is significantly heightened by the nature of the hazard itself—hypothermia. Hypothermia occurs when the body loses heat faster than it can produce it, causing a dangerously low body temperature. In the context of diving, this risk is magnified because the water conducts heat away from the body approximately 25 times faster than air. A malfunctioning valve that causes a sudden loss of inflation means the diver’s thermal protection vanishes almost instantly. This is not merely an inconvenience; it is a life-threatening emergency where the diver must make immediate decisions about surfacing while potentially experiencing confusion, loss of motor control, or unconsciousness due to cold shock and subsequent hypothermia.

While no specific age demographics are highlighted in the recall data, certain divers may be more susceptible to the consequences of such a failure. Older adults or those with pre-existing health conditions may find it harder to recover from cold shock or manage the physical exertion required to surface safely in an emergency. Additionally, technical divers who operate at greater depths and longer durations are often in colder waters for extended periods, relying heavily on their equipment’s integrity for survival. If the valve fails during a deep dive, the margin for error is slim, and the physiological stress of dealing with sudden thermal protection loss can overwhelm even experienced swimmers.

It is also important to note that this risk applies regardless of whether the diver purchased the suit new or used, as long as it contains one of the affected model numbers. The defect is internal to the valve mechanism, meaning the external appearance of the gear may look perfectly normal. Consequently, every individual who has interacted with SI Tech dry suits or these specific inflation valves since they were manufactured should be considered potentially at risk until they verify their equipment against the recall list and obtain a free replacement.

How to tell if you have the recalled item

If you are a recreational or technical diver who owns a dry suit equipped with an SI Tech Shell Inflation Valve, it is critical to verify whether your specific unit is part of this recall. Because these valves are integral to maintaining safe air pressure and thermal protection underwater, confirming their identity is not just a bureaucratic step—it is a vital safety check. The first thing you need to know is that the affected product is specifically the SI Tech Shell Inflation Valve with International Nipples. This component may have been sold as part of a complete diving dry suit package, or it might have been purchased separately as an aftermarket upgrade for an existing suit. Regardless of how you acquired it, if your gear features this brand and type of valve, you must inspect the hardware directly.

To determine if your valve is among those recalled by the Consumer Product Safety Commission, you need to look closely at the physical construction of the device itself. The identification marks are not on the packaging or a receipt, but stamped directly onto the metal body of the valve. Specifically, you should examine the inside of the recalled valve for two distinct pieces of information: the Model Number and the Batch Code. These markings are small and precise, so you may need good lighting and perhaps a magnifying glass to read them clearly. The model numbers associated with this recall are extensive, as they cover various configurations used in different diving scenarios. Your valve is potentially affected if it bears any of the following model numbers: 25210 JD1, JE2, JE5, JE6, JF6, JG2, JK6, JK9, JKA, JL1, JL3, KA7, KB8, KG2, KH3, KH4, KK7, KL3, LC1, LC2, LC4, LC7, LC9, LD2, LD6, LD7, or LD8. Additionally, valves with model number 25215 are included if they have the suffixes JG1, KA9, or LC5.

While the model number is your primary filter, the batch code provides the final confirmation of whether your specific unit was manufactured during the problematic timeframe. If you cannot locate these stamps on your valve, or if you need help deciphering what the codes mean, SI Tech has provided a dedicated resource to assist consumers. You can visit their official website at www.sitech.se, where they have posted detailed instructions on how to find and identify the batch code. This step is essential because having the correct model number is only half the equation; without verifying the batch code against their records, you cannot be certain if your specific valve was included in this April 14, 2022, recall action. Once you have identified both numbers, do not guess—verify them against the official list or contact Ocean Equipment directly to confirm your status before using the gear again.

What to do — step by step

Your refund, repair, or replacement options

If you own a diving dry suit equipped with the recalled Shell Inflation Valve by SI Tech, the good news is that the remedy for this safety issue is straightforward and entirely free of charge. You do not need to purchase a new valve, nor will you be responsible for any shipping costs associated with returning the defective part. The recall process is designed to be as seamless as possible for divers who rely on their gear for recreational or technical diving. Your primary option here is a repair via replacement, handled through authorized technicians who are exclusively trained to update your valve with a safe, compliant replacement part.

To initiate this process, you must contact Ocean Equipment, the designated remedy provider for this recall. You have several convenient ways to reach them. You can call their toll-free number at 800-657-7736 between 9 a.m. and 4 p.m. Pacific Time, Monday through Friday. If you prefer written communication, you may send an email to sitech@oceanequipment.ca. Alternatively, you can visit the Ocean Equipment website at https://oceanequipment.ca/ and look for the "Recall Notice" link located at the very top of the page. Another reliable resource is the manufacturer’s dedicated recall page at https://www.sitech.se/articles/recall.aspx. These channels are monitored specifically to handle this recall, ensuring you get accurate information without navigating general customer service queues.

Once you make contact, Ocean Equipment will provide you with a notification form and detailed shipping instructions. This is a critical step because the defective valve must be returned to them for proper disposal and replacement. Do not attempt to fix or replace the valve yourself using third-party parts, as this could compromise the integrity of your dry suit’s inflation system and thermal protection. Only the authorized replacement part installed by trained technicians will restore the valve’s ability to properly inflate the suit and equalize air pressure while you descend.

The "repair" in this case is effectively a component replacement rather than a full suit refund, as the issue is isolated to the inflation valve mechanism. However, the cost of the new part and the return shipping label are covered by the remedy program. This approach ensures that your dry suit remains fully functional and safe for future dives without imposing financial burdens on consumers. By following these steps promptly, you ensure that your gear meets current safety standards and continues to provide the essential thermal protection required for diving in cold waters.

What can happen if you ignore it

When you choose to keep using a diving dry suit with the recalled SI Tech Shell Inflation Valve, you are not just accepting a minor inconvenience; you are stepping into a situation where your body’s primary defense against the cold water is silently failing. The core function of this valve is to allow divers to inflate their suits as they descend, adding air to maintain pressure equalization. This process does two critical things: it keeps the suit from collapsing around your body and, more importantly, it creates an insulating layer of trapped air that protects you from the rapid heat loss of the surrounding water. If the internal mechanism malfunctions due to the defect identified in this recall, that inflation process stops working correctly.

The immediate physical consequence is a sudden and unexpected loss of thermal protection. In recreational and technical diving, hypothermia is not just about feeling chilly; it is a serious medical emergency that can impair judgment, reduce dexterity, and lead to unconsciousness or death. When the valve fails, the air inside your suit may escape or fail to expand as needed, allowing cold water to come into direct contact with your skin or compressing the insulating layer against your body. This accelerates heat loss dramatically. Because this malfunction can happen while you are underwater and potentially deep or far from the surface, you lose the ability to easily warm up or signal for help effectively. The lack of thermal protection means your muscles may stiffen, making it harder to swim or operate equipment when you need them most.

While SI Tech has so far reported three incidents where the valve malfunctioned and resulted in a loss of inflation, the fact that no injuries have been reported yet is a matter of luck rather than safety. Diving environments are unpredictable. A similar failure occurring at greater depth, in colder water, or during a complex dive could easily lead to severe hypothermia, panic, or drowning. Ignoring the recall means you are gambling with this possibility every time you enter the water. The recalled parts are not just "worn out"; they have a specific design flaw that can cause them to fail without warning. Continuing to use them ignores the clear evidence that the component is unreliable. By waiting, you are also delaying your own safety, as the longer you use the defective valve, the higher the statistical chance that it will fail during a critical moment. The remedy offered—free replacement by trained technicians—is designed specifically to eliminate this hidden risk. Choosing not to act leaves you vulnerable to a hazard that has already been proven to compromise the very system meant to keep you alive in the water.
