Petcock Bung 1/4 inch NPT Aluminum Weld-In – 4-pack

This weld-in aluminum bung allows you to change or move your fuel valve / petcock location to wherever you desire on your gas tank. Also very useful for oil tank fittings. 1/4″ NPT thread, aluminum. Made in the USA. Sold in a 4 pack. National Pipe Thread (NPT) is a U.S. standard for tapered threads used on threaded pipes and fittings. The taper on NPT threads allows them to form a seal when tightened. These are NOT used for mounting bungs as standard bolts do not fit into the tapered NPT threads.
