    1/2″ Brass Insert for Nylon Air Brake Tubing – DOT Approved

    Part #: MM-38-042

    This 1/2″ brass insert is designed for use with SAE J844 Type A nylon tubing in D.O.T.-approved air brake systems. It reinforces the tubing connection when used with compression or push-to-connect fittings, ensuring a secure, leak-resistant seal. Made from durable brass for corrosion resistance and long service life in pneumatic and brake line systems.
