Key Features & Benefits

Basically, this little piece connects three air lines together, but it does it through a solid block—that’s what the “bulkhead” part means. It allows you to tap into an existing air line without cutting or disrupting it completely. Think of it like a T – connector, but built to go through something – usually a wall or frame in the truck. It's designed for air brake systems specifically, so it needs to handle the pressures those systems operate at. In your truck or trailer, you’ll find these used in a bunch of places within the air brake lines. Often, it's to connect things like gauge lines, control lines for lift axles, or even supply air to an auxiliary system. It's a key connection point. You’ll notice it if you’re looking at the air lines running to things like the air dryer, or near the brake chamber connections. It’s rarely a visible part unless you’re actively working on the air system.

Symptoms, Risks & Replacements

This is one of those parts where failure isn’t really an option. Air brakes are obviously safety critical. This fitting acts like a shield, ensuring that air doesn’t leak out under pressure. Even a small leak can reduce braking effectiveness, and obviously, that’s dangerous. They’re generally very reliable, but vibrations and corrosion can eventually take their toll. If you start seeing air leaks around one, it needs to be replaced immediately. You can find these pretty easily – Fixparts Online has a good selection of them, along with everything else you need for your air brakes.
