PETCOCK - Part Number 21-101
U.S.A. Made with ball valve and built-in gas line spigot. Includes filter screen. Cadmium plated. Import Petcock Information Petcock openings in our tanks are either 3/8" or 1/4" NATIONAL PIPE THREAD, the same thread used in iron water pipe. The actual size of the hole in the tank is approximately 3/4" for the 3/8" NPT and 1/2" for the 1/4" NPT. Pipe thread is used because the thread is designed to seal against leakage as the petcock is screwed into the tank. It is not possible to screw the petcock all the way in flush with the gas tank.
