These fittings connect sections of the air lines in your braking system. Think of them like links in a chain – they allow you to join the air hoses and tubing securely without leaks. They’re typically used where you need a strong, permanent connection. They have threads on the outside that screw into a port, and a way to connect the air line itself, usually a barb or a compression fitting built right in. Basically, it's a vital part of how your air brakes work. Air pressure is what actually stops a big rig or a vehicle with air brakes, and these fittings ensure that pressure gets from the compressor, to the control valve, to the brake chambers without any loss. They're scattered throughout the whole air system – connecting the reservoir to the compressor, the compressor to the dryer, and on and on. If one of these fittings fails, you’re going to have an air leak. It might start as a slow leak you barely notice, but it can grow quickly. Even a small leak compromises the entire braking system. You’ll notice if your air compressor is running more often than usual, or if your brakes feel spongy. That’s a sign you've got a leak somewhere. Because air brakes are so critical for safety, you really want to address these immediately. You can find a good selection of these screw – in fittings, along with everything else you might need for your air brake system, over at Fixparts Online. It's always best to replace a faulty fitting rather than try to patch it. Wabco stands behind its products: Screw-In Fitting (MPN 8938008072) has a 12-month warranty!
