Key Features & Benefits

These are pretty simple parts. Basically, they cap off openings in your air brake system lines or components – things like ports on your air dryer, reservoirs, or even valves. They create a sealed connection to prevent air leaks. Sometimes they're used during assembly, other times to plug a line you've disconnected for maintenance. They’re usually made of metal, sometimes plastic, and they typically use an O – ring to make that airtight seal. It’s a small part, but vital for the whole air brake system to work right. Think of it like plugging a hole in a dam – without it, you lose pressure. In a vehicle, that pressure is what activates your brakes. It’s part of the air lines that run throughout your truck or trailer, making sure everything gets the air it needs when you hit the pedal.

Symptoms, Risks & Replacements

Well, air brakes rely on, as the name suggests, air. Any leak, even a small one, reduces the air pressure available to actually stop the vehicle. This plug acts like a shield, preventing those leaks. You’ll notice if you have a leaking plug because your air compressor will be running more frequently to try and keep up with the loss, and eventually, you’ll start getting low air pressure warnings. It's a cheap part to replace, and a really important one when it comes to safety. You can find these pretty easily, actually; we stock a good range, and Fixparts Online has a lot of options if you’re looking for something specific. Don’t want to mess around with something like this if it’s damaged or missing.
