Nemrod Snark exhaust valve reproduction in food grade silicone BLUE

Ok, we have been asked for years to make these so here we go. They are reproduction in food grade silicone and come in blue in honor of Nemrod's early blue hoses. They are fantastic and if you have an old Snark that has a hard neoprene valve in it don't despair silicone is here. Simply lube the nipple with a little hand sanitizer and pop it in the wagon wheel and let it dry. This valve will outlast your diving career.
