Wabco 8938039890 Push-In Coupling

Description

The Wabco 8938039890 Push-In Coupling is a critical component within air brake systems, designed to connect air lines securely and efficiently. This coupling is used in the construction and maintenance of commercial vehicle air brake systems, ensuring reliable pneumatic connections. Its OE specification guarantees compatibility and performance, while the robust construction enhances durability and reduces the risk of leaks. This coupling features dimensions of 29 x 40 x 36 mm and is designed for use with M26 x 1.5 threads and 18 x 2.0 tube diameters. The wrench size is 32.0 mm.

Key Features & Benefits

These couplings basically connect sections of air brake line together. They do exactly what they sound like – you push the lines into them and they create an airtight seal. They’re designed for quick, easy connections and disconnections, much simpler than threading everything. They handle the compressed air that runs your brakes, so it's all about secure, leak – free connections. Think of it like a link in a chain. Your whole air brake system relies on pressurized air getting from the compressor to the brake chambers at each wheel. This coupling is one of those connections that keeps that air flowing. You’ll find them throughout the air lines, connecting various components like the compressor, air dryer, reservoirs, and ultimately, to the brakes themselves.

Symptoms, Risks & Replacements

Well, if one of these leaks, or comes apart, you lose air pressure. That’s a big deal with air brakes. You’ll notice if you start losing pressure because your gauge will drop and you might even hear a hiss. Losing air pressure means reduced braking power, and that's obviously dangerous. These couplings are designed to be really reliable and prevent those leaks. They act like a shield against air escaping. You can find these pretty easily at places like Fixparts Online, and replacing a faulty one is usually a straightforward job. They're a small part, but a critical one for safety.
