The 5/8 x 3/4 Plastic PP DOT Tube OD 45 deg Male Elbow is a DOT-approved air brake fitting designed to connect a push-to-connect DOT tubing to a male pipe thread (MPT) at a 45-degree angle. This fitting is widely used in air brake systems, pneumatic applications, and industrial fluid transfer, offering a secure, leak-proof, and vibration-resistant connection.

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.
