Universal fit
This is a universal push-to-connect fitting suitable for any heavy-duty truck or trailer air system using 3/8 inch SAE J844 A/B tubing where a 1/4 inch male NPT connection is needed. It is intended for non-brake air applications such as air bags, air seats, and air controls; Imperial Supplies notes it does not meet SAE/DOT specifications for air brake applications. Always verify application and DOT compliance before installing on a brake circuit.

The fitting lets you join 3/8 inch outside diameter SAE J844 type A or B nylon air tubing to a port or component that has a 1/4 inch male NPT pipe thread. You would typically replace this when an existing air line fitting becomes cracked, corroded, worn out, or starts leaking air, causing a pressure drop or an audible hiss around the connection. It is commonly found in non-air-brake systems like air suspensions, air seats, cab air bags, and air-powered controls and instruments.
