This Taprite Beer Faucet Shaft Valve Seat O-Ring is made out of rubber and is meant to serve as a replacement part for standard Taprite Beer Faucets. Replace your non-functional shaft valve seat o-ring and return functionality to a useless faucet. Fix your leaky Taprite beer faucet with this (among other) o-rings, washers, and gaskets. It attaches to the shaft valve seat near the threaded end of the faucet.
