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.
PTC Fitting Advantages
Shorten assembly time: Say goodbye to the tedious assembly process associated with compression fittings. Our push-to-connect design reduces assembly time by up to 90%.
Versatility: Push connect air fittings are incredibly versatile as they are compatible with a wide range of vehicle systems including trucks, trailers, and rail systems.
Standards Compliance: D.O.T. and SAE specifications are stringent international requirements for DOT composite fittings, and these standards prove that DOT fittings are perfectly suited for each application.
Leakproof Design: Given the critical nature of pneumatic braking systems, a leak-free design is essential. Brass composite fittings are designed to be completely leak-free, allowing the braking system to operate safely.
Ease of Service: Composite dot air fittings make servicing a breeze for fleet managers, repair shops and implement dealers.
Applications
Buses
Designed for city buses and coaches, our D.O.T. quick connect couplings offer unmatched reliability and performance. Whether you’re traveling through a busy city or on a long highway, these couplings ensure that your air brake system operates flawlessly. In addition to primary and secondary brake lines, they are perfect for other pneumatic applications such as door systems, pneumatic seats and in-cab controls. Simplify maintenance and increase the safety of your passenger transportation operations with these quality fittings.
Heavy Duty Trucks
Our D.O.T. push to connect fittings are the preferred choice for heavy duty trucks that require a rugged and reliable air brake system. These fittings excel in both primary and secondary brake line applications, providing unmatched performance and safety. In addition to air brake systems, they are perfect for tire inflation systems, providing fast, leak-proof connections that stand up to the toughest conditions. By dramatically reducing installation time – up to 90% faster than traditional compression fittings – these composite push-in fittings have become a key part of keeping fleets running efficiently.
Trailers
The safety and performance of trailers is critical, especially in air braking systems. Our couplings provide an extra layer of assurance by not only meeting but exceeding D.O.T. and SAE performance requirements. These couplings are not limited to air brakes, however; they are also well suited for other pneumatic applications within the trailer, including air suspension and auxiliary systems. They feature a quick-connect design for fast assembly and maintenance, which is critical to keeping your trailer up and running.
