Description

Key Features & Benefits

This part basically joins two sections of air brake line together. It’s a coupling, if you will. The “double” part means it accepts two lines, and the locknut is what secures everything tightly. It creates a sealed connection so your compressed air doesn’t leak out. It’s a pretty simple part, but vital. This sits within your truck or trailer’s air brake system – you’ll find it anywhere two lengths of air line need to be joined. Think of it like a link in a chain. It's not directly doing the braking, but it enables the brakes to work by maintaining air pressure. They're common in the supply lines, control lines… pretty much anywhere air needs to travel to activate the brakes.

Symptoms, Risks & Replacements

Air brakes rely on pressure, pure and simple. If you have leaks anywhere in the system, you lose pressure, and that affects stopping power. This connector, when it’s good, acts like a shield against those leaks. You’ll notice if one of these starts to fail – you might get a hissing sound, or your air compressor will be working overtime trying to maintain pressure. Losing air pressure isn’t something you want to mess with, obviously. We carry a good selection of these at Fixparts Online, and getting the right size and rating for your system is key, so make sure you’ve got the correct one. A small part like this really is a critical safety component.
