silicone exhaust valve
had a hard time finding a replacement locally all the dive shops said time to get a new mask. found this online with a reasonable price but wasn't offered free shipping so paid $5. and some change which seemed a little high for the size of item. easy to put in arrived quickly and works really well.

Exactly as ordered
Exactly what I ordered, fast shipping, adequate price.  Moreover, unavailable for the price anywhere online, surprisingly; amazon's cheapest vendor requested over $10 for the same product.  It should not cost that much to replace a small valve.  I really did not want to throw my son's snorkel because someone pulled the valve out.

Ordered this item to fix my mask, and it was shipped quickly and fit perfect. It took less then 30 seconds to fix.

Hi, Thanks for your question. As long as the diameter is .75 inchs, and it is the same style,it should work. Thanks Divemaster Chris
