They are DOT compliant, meaning they meet the safety standards set by the Department of Transportation. These fittings are designed to connect the brake lines  in a vehicle's air brake system, allowing for efficient and effective braking. The push-to-connect design of these fittings makes them easy to use and install. They work by simply pushing the tube into the fitting until it clicks into place. The fitting uses a collet to hold the tube securely in place, ensuring a tight and leak-free connection. One of the advantages of using air brake push-to-connect fittings is that they eliminate the need for special tools or expertise. Anyone can install them, even those with no previous experience with air brake systems. The fittings are designed to be intuitive and easy to use, which makes them an ideal choice for DIYers and professional mechanics alike. Another advantage of these fittings is their versatility. They come in a wide range of sizes and configurations (unions, connectors, 45°elbow, 90°elbow, fixed or swivel, run tee, branch tee), allowing them to be used in a variety of applications. Whether you need to connect brake lines in a truck, bus, or other type of vehicle, there is a push-to-connect fitting that will meet your needs. Finally, air brake push-to-connect fittings are incredibly reliable. They are designed to withstand the high pressures and temperatures that are typical in air brake systems, and they are built to last. When you use these fittings, you can have confidence that your brake system will function properly and safely. In summary, air brake push-to-connect fittings are an essential component.
D.O.T Air Brake Brass Fittings DOT NTA brass fittings for air brake systems are an essential component of air brake systems. They are used in conjunction with SAE J844 Type A and Type B nylon tubing, as well as in-cab air controls. These fittings are ideal for use in most air brake systems, with the exception of those where the temperature is under -40°F(-40°C) or above +200°F(+93°C), or where battery acid can drip on the tubing. One of the main advantages of DOT NTA brass fittings is that they meet D.O.T. FMVSS 571.106 air brake specifications. This means that they are designed to meet the highest standards for safety and reliability in air brake systems. Additionally, these fittings meet the functional requirements of the SAE 246 & SAE J1131, ensuring that they are compatible with other components of air brake systems. DOT NTA brass fittings are machined from CA360 brass, which is a high-quality, corrosion-resistant alloy that is well-suited for use in air brake systems. This material is strong and durable, making it ideal for use in harsh environments where it may be subjected to high pressures, vibration, or temperature extremes. Another significant advantage of DOT NTA brass fittings is that they are easy to assemble. They do not require any tube preparation or flaring, and they come with a built-in tube support to help ensure a secure fit. This makes them ideal for use in situations where time is of the essence, or where assembly must be done quickly and efficiently. In summary, DOT NTA brass fittings are a reliable, high-quality component of air brake systems. They meet the highest safety and reliability standards, and are compatible with other components of air brake systems. Their use of durable materials and ease of assembly make them an ideal choice for many applications.  
Air Brake Metric Push In Coupling Air Brake Metric Push In Coupling is an essential component used with DIN74324 or DIN73378 tubing, which are widely adopted in the compressed air circuits of commercial vehicles. Crafted from brass and fortified with an EPDM O-Ring, these couplings are not only robust but also perform exceptionally well under harsh conditions, with an operating temperature range of -40°C to +100°C. A salient feature of this coupling is its user-friendly design that facilitates easy and quick assembly . The coupling is designed for maximum flexibility, with the capacity to be connected and disconnected multiple times, demonstrating its reusable nature. The coupling ensures a high level of reliability with a positive seal. Once the tubing is inserted, a tight seal is formed that prevents any leakage, making it a highly reliable solution for your pneumatic applications. However, it is crucial to note that the use of these couplings with media other than air is strictly not advised without prior approval. Overall, the Air Brake Metric Push In Coupling is a trustworthy, durable, and versatile solution for maintaining efficient air circuits in commercial vehicles.
Reusable Hose Fittings for Air Brake Hose Applications: Used with SAE J1402 rubber hose Type A in air brake system, except for where temperature is under -40°F(-40°C) or above +212°F(+100°C) or where battery acid can drip on tubing. Advantages: Meet D.O.T. FMVSS 571.106 air brake specifications. Meet functional requirements of SAE J1402. Easy to assemble and disassemble Reusable (body and nut are reusable) Notes: When reassembling fittings and hoses, the fitting body and nut should be inspected.Only if the parts are in proper condition, can they be reused. SLEEVE SHOULD BE NEVER REUSED. Material: C36000 brass Finish: Plain For 3/8 and 1/2 Rubber Hose 1/4”NPTF, 3/8”NPTF, 1/2”NPTF are available Reusable hose ends are a great solution for those who need to repair or replace their SAEJ1402 air brake hose.
