Key Features & Benefits

This plug basically seals off an air brake line when you disconnect a component for service, or sometimes it’s used when an air fitting isn’t being used at all. It prevents air and moisture from getting into the system. It's a pretty simple part, but crucial for keeping everything clean and working right. It creates a tight, secure seal. It’s part of your air brake system, obviously, and you'll find them used on air lines connected to things like air tanks, compressors, even some of the valves. They're there to cap off those ports when things aren’t actively connected. You’ll notice if you have one missing because you’ll likely hear a slight air leak, and potentially see moisture build up around the open connection.

Symptoms, Risks & Replacements

Air brake systems rely on clean, dry air. Water and dirt can cause corrosion, freeze in cold weather, and just generally mess things up. This plug acts like a shield, preventing that from happening. A leaking or missing plug can introduce contaminants, leading to bigger problems down the road—like worn seals, failing components, or even a loss of braking power. It’s a small part, but keeping it in good shape is part of maintaining a safe and reliable air brake system. You can find these pretty easily, we actually have a good selection at Fixparts Online, but a lot of auto parts stores will carry them too.
