TC Bros. 1/4" NPT (National Pipe Thread) bungs are most commonly used for gas tank petcock bungs or for oil tank fittings.
Proudly made in the USA from premium American 1018 cold rolled steel for easy welding.
Note: NPT threads are tapered. They are only designed to be used with corresponding NPT threaded fittings or pipe. The tapered design allows the threads to create a leak proof seal when tightened. They are not to be used with standard bolts or hardware.
These bungs install easily by inserting into a 3/4" diameter hole and welding around the 1" diameter flange. See photos for all dimensions.
