The 1/2 x 3/8 Plastic Push-In DOT Union Tee is a T-shaped push-in fitting designed to connect three sections of OD tubing securely. It allows for branching air or fluid lines while maintaining a leak-free and durable connection. This fitting is commonly used in DOT-approved air brake systems, pneumatic applications, and industrial fluid transfer systems.

This D.O.T. and SAE compliant composite fitting features a one-touch push-to-connect design that reduces installation time by up to 90% compared to traditional compression fittings. Its UV- and vibration-resistant composite body offers a lightweight, corrosion-proof solution that is roughly 43% lighter than brass, improving vehicle fuel efficiency and payload capacity. The positional swivel allows the elbow to be threaded into a port first and then rotated 360° to the perfect angle for your tubing run, ensuring a clean and secure installation.
