Air Valve Bolt Rubber Seal
Rubber seal only for any air valve (also known as a 'vent screw' or 'board plug') that screws into the deck of any (non-breathable valve) windsurf board to keep the water out.
Buy this item to replace lost or damaged ones or as a spare. Keep an eye on the condition of the seal and replace when necessary to avoid water ingress.
