001321199 Audi O-RING

They create a seal. Basically, they sit between two parts that need to be airtight or watertight and fill any tiny gaps. Think of it like squeezing a rubber band around a joint—that’s the idea. They come in different materials, like nitrile or silicone, depending on what fluids they’ll be exposed to—oil, coolant, fuel, that sort of thing. You’ll find them everywhere in your engine and throughout the vehicle really. Fuel lines, oil filters, water pumps, anywhere fluids need to stay contained. They’re often used in places where things move, so they need something flexible to maintain the seal. Sometimes they’re in pretty simple spots, sometimes they’re buried deep inside something. If an O – ring fails, you’re going to have a leak. It might be a slow drip, or it could be a pretty significant spill. That can lead to all kinds of problems, from reduced engine performance to serious damage if fluids get where they shouldn’t. You’ll notice if one goes bad, usually by seeing a fluid leak or sometimes a drop in fluid level. They're a small part, but they act like a shield preventing bigger, more expensive issues. You can find a pretty good selection of O – rings at places like Fixparts Online—they usually have the right size and material for most applications. Don’t underestimate these little things, they keep everything running smoothly. Year-round reliability: O-Ring (MPN 001321199) includes a 12-month warranty!
