The Bronze Bushing is a critical component within air brake systems, specifically used in air compressors. Manufactured by Wabco with MPN 4111412054, this bushing provides a smooth, low-friction surface for moving parts within the compressor. Its dimensions are 20 x 4 x 34 mm, ensuring a precise fit and reliable operation. This component is designed to meet OE specifications, delivering enhanced durability and performance for extended service life and reduced maintenance costs. This little bushing basically lets parts move smoothly against each other. Specifically, it sits between the piston and the connecting rod inside the air compressor. It acts like a cushion, reducing friction as those parts go back and forth. It's a simple part, but crucial for how things operate. Your air compressor is what builds up the air pressure that runs your brakes – and a lot of other things, depending on your vehicle. It pumps air into the reservoirs, and that pressurized air is what actually makes the brakes work when you hit the pedal. This bushing is inside that pump, helping it run efficiently. It's a small piece of a much bigger system, but you'll notice if it fails. Without a good bushing, that piston and connecting rod are going to wear down really quickly from all that friction. It’ll start making noise, and eventually the compressor won’t be able to build up enough pressure. That means your brakes won't work reliably, and that's a serious safety issue. They don’t last forever, of course, and are considered a wear item, so replacing it regularly helps prevent a bigger, more expensive breakdown. You can find these at places like Fixparts Online, and it’s a pretty straightforward repair if you’re comfortable working on your air system. It’s a small part that prevents a lot of headache. We stand behind our products: Bronze Bushing (MPN 4111412054) has a 12-month warranty!
