The Wabco 8930402304 Sleeve Insert is a critical component within air brake systems, specifically used in fittings to ensure secure connections and prevent air leaks. This sleeve insert is designed for use in pneumatic lines connecting various brake system components. It is manufactured to OE specification for reliable performance and durability. Measuring 10 x 12 x 15 mm, this component provides a precise fit and contributes to the overall efficiency and safety of the braking system by maintaining consistent air pressure. 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. Customer-approved reliability: Sleeve Insert (MPN 8930402304) includes a 12-month warranty!
