When Safety is Non-Negotiable, Trust Vintage Parts Revival
For your truck or trailer's air brake system, there is zero room for compromise. At Vintage Parts Revival, we've sourced these New Old Stock (NOS) D.O.T.-approved air brake fittings for precisely that reason. Manufactured from solid brass to a standard of quality that’s hard to find today, these fittings offer the rugged reliability required for safety-critical systems. Don't settle for modern plastic fittings when you can have the durability of heavy-duty, corrosion-resistant brass.
This straight connector is designed for fast, secure, and serviceable connections in any air brake system. The 3/8" Push-to-Connect (PTC) end allows for instant, tool-free installation of standard 3/8" OD nylon air brake tubing. The 1/4" NPTF (Dryseal) male end comes with pre-applied thread sealant, providing a secure, leak-free connection right out of the box into air tanks, brake chambers, valves, and other system components.
Most importantly, each fitting is stamped "D.O.T.", certifying that it meets or exceeds the stringent standards of the Federal Motor Carrier Safety Administration (FMCSA) for use in commercial vehicle air brake systems. Keep your rig safe and compliant with genuine, high-quality hardware.
