It connects 1/4” outside diameter DOT nylon tubing to a 1/4” male NPT threaded port. The swivel design lets you install it in tight spaces without twisting the tubing. It’s used for heavy-duty truck and trailer air brake systems, suspension controls, and auxiliary pneumatics. Replace it when you need a leak-free, durable brass connection that meets DOT FMVSS-106 standards.
