Snorkel and mask purges employ thin, flexible valves to maintain a one-way passage for air or water. Over time, through repeated use these valves become worn and lose their ability to seal properly. If this has happened to your favorite IST SN18 snorkel’s purge, the IST Replacement Silicone Exhaust Valve for SN18 Snorkel can instantly solve your purge problem.
Constructed of hypoallergenic silicone, this part replaces your SN18 purge valve with just a couple of easy steps. Disassemble the bottom of your snorkel, below the mouthpiece. Remove the old valve from the purge, pop in the new one and reassemble the snorkel. That’s all there is to it!
Keep a spare on hand so you’ll be ready to replace your SN18 purge valve when age catches up with it.
