This sleeve is a critical component within air brake systems, specifically used as a fitting to connect tubing and ensure proper air flow. It's designed for use in heavy-duty vehicles and trailers. This Wabco sleeve, with MPN 8930402504, maintains system integrity and reliable brake performance by providing a secure and leak-proof connection. The dimensions of this sleeve are 15 x 12 x 12 mm, and it's manufactured to OE specification for optimal compatibility and durability. These little guys basically connect pieces of air line together. They slide over the ends of the air lines and then a fitting – like a connector or elbow – goes into the sleeve, then everything gets tightened down. They create a tight, secure, airtight seal. They come in different lengths depending on how much overlap you need and sometimes have different coatings for corrosion resistance. Think of your air brake system like the veins and arteries in your body; it needs to get air where it needs to go, reliably. The sleeves are a small but crucial part of that network. They're used all throughout the air lines – connecting the compressor to the tanks, tanks to the valves, valves to the brake chambers… everywhere. They ensure a solid connection throughout the entire system. If these sleeves are cracked, damaged or missing, you’ll have air leaks. And air leaks in a brake system? That’s a big deal. It can lead to reduced braking performance, longer stopping distances, or even a complete brake failure. They’re a small part, but they act like a shield, protecting the connection and keeping the system sealed. You’ll notice if one is bad because you might hear a hissing sound, or your air compressor will be running more than it should to keep up with the lost air. You can find a good selection of these at places like Fixparts Online, and it's usually a good idea to replace them any time you're working on the air lines anyway – just to be safe. It’s a cheap part that can prevent a very expensive and dangerous problem. Year-round reliability: Sleeve (MPN 8930402504) includes a 12-month warranty!
