The 1/4 in. x 3/8 in. Plastic Composite DOT 45 Male Elbow is a DOT-compliant push-to-connect 45° elbow for commercial vehicle air brake tubing systems. DOT push-to-connect fittings meet SAE J844 and FMVSS 106 requirements for air brake lines — they are specifically rated for the pull-out force, operating pressure, and temperature requirements of truck, trailer, and bus air brake circuits. A single push seats the nylon air brake tubing; press the release collar to disconnect.
