Key Features & Benefits

This little piece connects sections of your air brake lines—typically the flexible rubber hoses—together. It’s designed to change the direction of the air line, letting you route things nicely and avoid kinks or rubbing. It seals tightly using a threaded connection and usually an O – ring or similar gasket inside to prevent air leaks. Essentially it’s a connector that lets the air flow where it needs to go. In your braking system, it’s a part of the network that delivers compressed air from the compressor, the air dryer, and the reservoir to the brake chambers on your wheels. This fitting will be somewhere along that line—you’ll find them connecting the various hoses and pipes. Because of its location, it's exposed to the elements and road grime, so it can corrode over time.

Symptoms, Risks & Replacements

Well, your air brakes rely on airtight connections. If this fitting leaks—even a little—you’ll gradually lose air pressure. You’ll notice if your brakes start to feel spongy or require more effort to apply, or even if the parking brake won’t fully release. It acts like a shield, keeping the system pressurized. A leak here isn’t just an inconvenience; it’s a safety issue. If you’re working on your air system, it's always a good idea to replace these fittings whenever you replace the hoses just to be sure. You can find a good selection of these at places like Fixparts Online, and they’re pretty straightforward to install if you’re comfortable with basic wrench work.
