It passes an air line through a frame rail or bracket, with a 1/2-inch tube socket on the outside and 3/8-inch NPT female threads on the inside. The 1.31-inch overall length and 7/8-20 mounting thread secure it into the frame. Replace when threads are stripped, the brass body cracks, or the fitting leaks air.
