Description
This O-ring is a small but very useful part in vacuum pumps. It is made from Viton, a tough rubber that handles heat and chemicals nicely. The inside diameter is 24.8 mm and the thickness is 1.5 mm, so it fits just right in its place.
It is designed for Leybold Trivac pumps, especially the D40BCS and D65BCS models. The O-ring goes inside the pump to block air, oil, or dirt from leaking. This helps the pump hold a strong vacuum and run without problems.
If you are fixing or maintaining a Leybold Trivac pump, this O-ring is a smart choice. It is easy to put in and helps your equipment stay reliable. Many people who work with these pumps keep a few on hand for regular service.
