8938301040 Wabco Male Stud Elbow Coupling

This little piece connects sections of air brake line, but it does it with a bit of a bend – that’s what the “elbow” part means. It has a male threaded stud sticking out, which screws into another part, usually a fitting on your air tank, compressor, or brake chamber. It seals everything up to maintain the air pressure needed for your brakes to work. It essentially creates a strong, airtight corner in your air line. Think of your air brake system like a network of pipes carrying air. This coupling is just one connector in that network. It's specifically used where you need to change the direction of the air line, usually around a chassis component or to make a neat connection. You’ll find these pretty commonly where the air tank connects to the rest of the system, or near the air compressor. Well, air brakes rely on air pressure. If you have a leak anywhere in the system, you lose pressure, and that's obviously dangerous. This coupling, when properly installed, acts like a shield against air leaks at that specific connection point. It’s a small part, but it plays a big role in keeping your brakes functioning reliably. You’ll notice if one of these starts leaking, because you’ll likely hear a hissing sound, and potentially see moisture around the fitting. If you're doing any work on your air lines, it’s always best to replace these fittings as a preventative measure. You can find these, and a lot of other air brake parts, over at Fixparts Online if you’re looking for a source. Durability you can trust: Male Stud Elbow Coupling (MPN 8938301040) has a 12-month warranty!
