PETCOCK - Part Number 21-106
These H-D new style petcocks are engineered without O-rings to insure against gas leakage while providing maximum flow. Has filter screen and a reserve. Chrome 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.
