Composite DOT Fittings

Products Feature

Our D.O.T. quick connect Plug-In Fittings are the industry standard when it comes to repairing and maintaining air brake systems on semi-trucks, trailers, buses, and a variety of other mobile equipment. These fittings meet D.O.T. FMVSS 571.106, SAE J2494-3, and SAE J1131 standards for the perfect balance of durability and efficiency. Manufactured from composite materials, these fittings are strong, lightweight, and impact-resistant, with stainless steel tube supports that meet the stringent requirements of SAE J2494-3 to ensure optimal flow.

Designed with ease of use in mind, these fittings greatly speed up the assembly process and save up to 90% of the time compared to traditional compression fittings. Push-to-connect air fittings are ideal for secondary air applications such as track pneumatic doors, pneumatic seats, and shock absorbers, providing a quick, leak-proof tube connection. Their versatility makes them a top choice for fleets, repair shops, and farm machinery dealers who need a fast, reliable solution for servicing nylon brakes and secondary airlines.

Known for its corrosion resistance and excellent electrical conductivity, brass stands up well to heavy-duty use and is a reliable choice for a variety of applications. Its durability ensures long-lasting performance and reduces the need for frequent replacement.

Composite materials are made up of materials such as plastic and can be used with brass fittings, offering the advantage of lighter weight and easier handling and installation when both of them are used together.
