Wabco 8938603840 Equal Tee Coupling

Description

The Wabco 8938603840 Equal Tee Coupling is a critical component within air brake systems, designed to join three sections of tubing while maintaining a secure and leak-proof connection. It's commonly used in heavy-duty vehicles and trailers to distribute compressed air throughout the braking network. This coupling features dimensions of 27 x 120 x 70 mm and is manufactured to OE specification, ensuring reliable performance and compatibility. It's engineered with precise thread sizes of M18 x 1.5 and tube diameters of 12 mm and 11 x 3.5 mm, resulting in a robust and efficient air distribution system.

Key Features & Benefits

This little piece connects three sections of air line together – basically, it’s a Y – shaped connector. It splits the air supply from a single line into two, or joins two lines into one. It’s a simple connection, but it needs to be airtight, that’s the key. It’s usually made of metal, often steel or brass, and relies on compression fittings and O – rings to create that seal. Think of your air brake system like a network of pipes delivering air to the brakes. This tee coupling is just one of those connectors, letting the air flow where it needs to go. You’ll find these used in a lot of places – maybe connecting the main air reservoir line to the brake chambers, or splitting the supply to different axles. It's part of the broader air distribution system.

Symptoms, Risks & Replacements

It’s important because leaks in the air brake system are serious. That air pressure is what stops your vehicle. Even a small leak can reduce braking power, and that can be really dangerous. This coupling, when it’s in good shape, acts like a shield, preventing air from escaping. You’ll notice if one of these starts failing because you might get an air leak sound, or your brakes might feel spongy. A failed coupling can throw an air brake warning light, too. You can find these pretty easily; a good place to start looking is Fixparts Online, they usually have a good selection. Just make sure you get the right size and thread type for your system.
