Key Features & Benefits

These little guys are basically seals. They’re designed to create a really tight, leak – proof connection inside air brake fittings. They get compressed when the fitting is tightened, and that compression is what stops air from escaping. They're not a big, complicated component, but they're essential for making sure everything's sealed up properly. Think of your air brake system like a network of pipes and connections. These rings sit inside those connections, primarily where air lines connect to things like the air dryer, reservoirs, or brake chambers. They’re used in pretty much any place you need a secure, airtight seal in that system. They aren't something you see directly – they’re inside the fitting itself.

Symptoms, Risks & Replacements

Well, air brakes rely on, unsurprisingly, air! If you've got a leak anywhere in that system, even a small one, it can cause all sorts of problems. You’ll notice if your brakes start feeling spongy, or if your air compressor is running constantly trying to keep up with the lost air. That constant running will wear out the compressor quicker too. A cutting ring acts like a shield, preventing those leaks and ensuring consistent, reliable braking performance. They're a cheap part to replace, honestly, and it’s a good idea to do them whenever you’re working on air lines or fittings just to be safe. You can find a good selection of them at places like Fixparts Online, they usually have exactly what you need. Replacing a worn out cutting ring is a lot easier, and cheaper, than dealing with brake failure down the road.
