Frequently Asked Questions
Which drysuits does the Bare Si Tech exhaust valve fit?
It is intended for drysuits equipped with SiTech exhaust valve systems and integrates with standard drysuit configurations. Valve bases and threads can differ between suit models and production years, so check the valve currently on your suit before ordering. If you are unsure, call 888-701-4017 or chat with us and we can help you confirm the match.
How many valves come with this item?
Packaging quantity is not published for this item. Contact us at 888-701-4017 and we will confirm before you order.
What does a drysuit exhaust valve actually do?
It vents air out of the drysuit in a controlled way. As gas inside the suit expands during ascent or shifts with body position, the exhaust valve releases it so the diver can manage buoyancy, avoid excess air buildup inside the suit and stay comfortable and stable through the dive.
Is this valve suitable for salt water diving?
Yes. The valve uses corrosion resistant construction selected for salt water use and for wear from regular diving. It is also built for underwater use and frequent venting cycles, per the product listing. As with all drysuit hardware, rinse the valve with fresh water after salt water dives and inspect it as part of routine suit maintenance.
