Key Features & Benefits

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.

Symptoms, Risks & Replacements

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.
