Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

Color-code your lines by snapping these rings over the release ring on low-temperature D.O.T. push-to-connect tube fittings.

Safely deliver compressed air to brakes in semitrucks, trailers, and other vehicles with this D.O.T. certified hose. Made of flexible nylon, it will bounce back to its coiled form even after long periods of use.

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required.
