The Wabco 8930402204 Sleeve Insert is a critical component used within air brake systems, specifically as a fitting to ensure secure connections. It's designed for use in pneumatic lines and contributes to the overall reliability of braking performance. This sleeve insert meets OE specifications, providing a precise fit and robust sealing capability. Manufactured in Germany, it measures 15 x 8 x 15 mm and accommodates tube diameters of 8 mm and 6 mm. These little guys are basically connectors. They slide inside air brake fittings – things like where your air lines connect to the air dryer, or the brake chambers. They create a tight, leak – proof seal between the airline and the fitting itself. They handle the pressurized air, so they need to be solid. Think of your air brake system like your circulatory system – everything needs to be sealed and working right for it to function. These inserts are a critical part of those connections. They ensure the air pressure goes where it needs to go – to your brakes – and doesn't escape. They fit inside the fitting to grab onto the air line and create that seal. Without them, you’ll get leaks, and that’s a big problem. Air brakes rely on consistent pressure. A leak, even a small one, can significantly reduce braking power and that’s obviously dangerous. These sleeve inserts act like a shield against those leaks. You’ll notice if one fails, usually as a slow or fast leak when applying the brakes, or a hissing sound. It's a cheap part to replace compared to the cost of fixing a brake failure. You can find them pretty easily—we stock a lot of them at Fixparts Online, and other auto parts places should too. Best to replace them any time you’re working with the air lines, just as a preventative measure. Professional-grade support: Sleeve Insert (MPN 8930402204) comes with a 12-month warranty!
