Over time silicone valves and related parts in snorkels become worn, gradually losing their ability to form a completely watertight seal. If this has happened to your favorite IST SN18 snorkel’s purge, the IST Complete Purge Valve Assembly with Housing for SN18 Snorkel can instantly solve your purge problem.
Constructed of hypoallergenic silicone in a plastic housing, this part replaces your SN18 purge with just a couple of easy steps. Disassemble the bottom of your snorkel, below the mouthpiece. Remove the old 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 when age catches up with it.
