It is typically used in air brake or air suspension plumbing on trailers and heavy trucks, where a smaller line or fitting must be attached to a larger port. The bushing is a simple, threaded brass or steel fitting that screws into the 3/4" opening and provides a 1/4" female thread. Over time, these bushings can corrode, crack, or suffer thread damage, leading to leaks in the air system; they are inexpensive and commonly replaced during system repairs.
