Description
This Leybold O-ring is often the simple part you need to fix it.
This O-ring is a ring-shaped seal. It fits into a groove between two parts of your pump. When compressed, it fills the gap completely, creating an airtight seal that keeps the vacuum strong.
It’s made from Viton, a special high-performance material. Viton is much tougher than standard rubber. It resists heat, oil, and harsh chemicals found inside vacuum pumps. This means it lasts longer and won’t crack or degrade quickly.
Using this exact part is crucial. Its dimensions—122 mm inside diameter by 3 mm thickness—are engineered for a perfect fit in your specific pump model. The right size ensures a tight seal, prevents leaks, and keeps your pump running efficiently.
This O-ring fits a wide range of popular Leybold Trivac and Ruvac pump models. If you’re doing maintenance on one of these pumps, having this seal on hand is a smart move. Replacing worn O-rings is key to reliable performance.
