The Wabco Oil Control Ring Iso6621-85x2 is a critical component within air brake systems, specifically used in air compressors to regulate oil flow and maintain optimal performance. This ring effectively controls oil consumption, preventing it from entering the air stream and ensuring clean, consistent air delivery for braking functions. Measuring 2 x 89 x 89 mm, this component meets OE specifications, providing a reliable and durable solution for maintaining air brake system efficiency. Its precise design and high-quality materials contribute to extended service life and reduced maintenance requirements. This ring’s job is pretty specific. It lives inside your air compressor – that’s the thing that makes the air for your brakes, and a bunch of other stuff. Basically, it scrapes excess oil off the piston as it moves up and down. It doesn't stop oil, it just controls it. It’s designed to let a very thin film stay on the piston for lubrication, but get rid of anything extra that could end up in your air lines. Think of it like a squeegee on a car windshield – it clears away the excess but lets a little stay for proper function. As I said, it’s inside the air compressor. The compressor pumps air into your air tanks, which then powers your brakes, things like your lift axles, and sometimes even your suspension. The oil control ring helps keep that air clean. Dirty air can damage valves and other parts of the air system, and that leads to problems down the road. It’s a small part, but it's vital to the whole system functioning right. If this ring wears out or breaks, you’ll start getting oil carried along with the air. You’ll notice if it's bad because you might see bluish smoke from the compressor, or you could see oil mist in the air lines. More importantly, it causes a loss of efficiency and can lead to expensive repairs on other components like the air dryer and brake valves. Replacing this ring is a lot cheaper than replacing a whole compressor or dealing with brake failure. You can find these at places like Fixparts Online, and they’re usually pretty straightforward to install if you’re comfortable working on air systems. It’s just a small rubber ring, but keeping it in good shape is a smart move. Built to endure: Oil Control Ring Iso6621-85x2 (MPN 8956704144) comes with a 12-month warranty!
