It joins 3/8" outside diameter (O.D.) nylon air brake tubing to a 1/2" male National Pipe Thread (NPT) port. The push-in design allows quick, tool-free installation, and the brass body with pre-applied thread sealant delivers a durable, vibration-resistant connection. Replace a cracked or leaking fitting to maintain consistent air pressure and safe braking on heavy-duty vehicles.
