This Thrust Washer, manufactured by Wabco under MPN 8930301704, is a critical component within air brake systems. It's designed to reduce friction and wear between rotating or sliding parts, ensuring smooth operation and extending the lifespan of the braking components. This washer is commonly used in fittings within these systems. With dimensions of 3 x 22 x 22 mm, this OE specification component is engineered for reliable performance and durability, contributing to the overall safety and efficiency of the air brake system. Basically, it's a small, often flat, piece of metal – sometimes steel, sometimes another durable material. It’s designed to reduce friction and wear between moving parts. Think of it like a buffer, or a really smooth pad. It handles forces pushing along the surface, not directly into it. It distributes that pressure evenly. Sometimes they’ll have a coating to help with that even more. In your air brake system – specifically with the fittings – it sits between components. When things move and tighten or loosen with pressure changes or normal operation, the thrust washer takes the brunt of that sideways force. It prevents metal – on – metal contact, and keeps everything sliding smoothly. It's usually found in areas where parts rotate or slide against each other, like around a brake chamber rod or where an air line connects. Well, without it, you’d get a lot of wear and tear on those fittings. They’d start to bind up, get corroded faster, and eventually, you could have leaks or even a failure. It acts like a shield, protecting the more expensive parts from damage. You’ll notice if one goes bad usually because things will start to feel sticky or slow when the brakes operate, or you might hear some squeaking or grinding. They’re small parts, but surprisingly important for keeping your air brake system working correctly and safely. You can find them pretty easily online – Fixparts Online has a good selection, if you’re looking for a source. Replacing them when you do other brake work is a smart preventative measure. Hassle-free support: Thrust Washer (MPN 8930301704) comes with a 12-month warranty!
