Design features
1.Quick-plug connection, with push-in connection design, no tools required, just push the proper tube directly into the fitting when installing, saves up to 75% assembly time compared to standard air compression fittings, and there are no loose parts to deal with.
2. Easy to disassemble, when disassembling, hold the ferrule ring with two fingers to pull out the tube, no tools required, easy to operate.
3. Reusable, able to connect and disconnect many times, with good durability and economy.
4. Reliable sealing, all male threads are pre-coated with PTFE-based pipe sealant, which ensures easy assembly and leak-proof sealing. A complete seal is guaranteed when using the recommended tubing. In addition, FKM "O" rings are used as standard to ensure reliable sealing performance in different environments.
5. Full-flow design, consisting of an all-brass fixed eyelet construction, allows maximum flow through. The brass fixed eyelet is long, floating design with a machined top radius for easy pipe installation.
Specific Applications
1. Truck / Trailer Brake System for connecting the main brake valve to the wheel brake air chamber to ensure rapid compressed air transfer. Its all-brass construction (C3600/C3700 alloy) withstands temperatures ranging from -40°F to 200°F and is stable at 150 psi.
2. Designed for emergency brake redundancy, the coupler quickly builds brake pressure in redundant braking systems, such as when the primary brake line fails, and activates the backup air line via a quick-connect to ensure emergency vehicle braking.
3.Trailer brake control, connects the brake control valve of the tractor and trailer for synchronized braking. Its FKM "O" ring and pre-coated PTFE sealant can prevent vibration-induced air leakage and adapt to complex road conditions.
