This part basically just joins sections of air line together. It’s a simple fitting, a tube that connects two pieces of air hose, letting the compressed air flow through the system as it should. It's designed to create a secure, airtight seal. They usually have threads on each end to screw into the other components. In your truck or trailer's air brake system, these connectors are everywhere. They’re part of the network of hoses and lines that deliver compressed air to the brakes, the air bags (if you have them), and other pneumatic components. Think of it like plumbing in your house – these connectors are the joints holding everything together. You'll find them connecting the air compressor to the reservoir, the reservoir to the brake chambers, and all along the lines that control the whole system. Well, air brakes rely on perfectly sealed lines. If you’ve got a leak anywhere, your brakes won't get the air pressure they need to operate correctly, and that’s a safety issue, plain and simple. These connectors, when in good shape, act like a shield against those leaks. You’ll notice if one starts to go bad because you might get a hissing sound, or you’ll see corrosion around the fitting, or even just feel a loss of air pressure over time. If it's cracked or damaged, it needs to be replaced. We carry a good selection of these at Fixparts Online, various sizes to make sure you get the correct fit for your system. It’s a small part, but crucial for keeping you safe on the road. Get more for your money: Straight Connector (MPN 8938000440) is covered for 12 months!
