Key Features & Benefits

Basically, this is a fitting that allows you to pass an air line – usually brake line – through a metal wall, like the frame of the vehicle or the chassis. It has threads on both sides - one to screw into a hole you drill or that's already there in the wall, and another side to connect your air line to. It creates a sealed connection, preventing air leaks. It's often used where you need to transition from exposed air line to one that's protected inside a frame rail. Think of it as a doorway for your air brake lines. It’s a crucial component in the air brake system, allowing the compressed air to travel from the compressor and reservoir to the brakes themselves. Specifically, it lets the air lines get through structural parts of the vehicle without compromising the seal. It's commonly found connecting lines running to rear brakes or air bags, things like that.

Symptoms, Risks & Replacements

Air brakes rely on perfectly sealed lines. If you have even a tiny leak, you lose braking power, plain and simple. This connector acts like a shield, protecting the connection point from damage and ensuring no air escapes. You’ll notice if one of these starts to fail; you’ll likely have a slow leak and eventually experience reduced braking performance. It’s a small part, but it plays a big role in keeping you safe. You can find these pretty easily, Fixparts Online has a good selection, and it’s a pretty straightforward repair if you need to replace one. It’s definitely something you don’t want to put off if you suspect an issue.
