DOT Push-to-Connect Fittings

DOT push-to-connect fittings are SAE J844- and FMVSS 106-compliant air brake tube fittings rated for commercial vehicle pneumatic brake systems — truck, trailer, bus, and heavy equipment air lines where federal DOT safety standards apply. The push-in collet grips nylon air brake tubing (1/4 in. to 1/2 in. OD) with a single push, eliminating compression sleeves and flaring tools while meeting the pressure, temperature, and pull-out force requirements of federal motor vehicle safety standards.
