Description
This O-ring is a small but very useful part in Rietschle vacuum pumps. It is made from Buna, a tough rubber that works well with oils and normal operating conditions. The inside diameter is 29.87 mm and the thickness is 1.5 mm, so it fits snugly where it belongs.
It is designed for many Rietschle models in the V-VC and V-VCA-VCE series. This includes pumps like VCA25, VCE25, VCA40, VCE40, VCA60, VCE60, VC100, VC150, VC200, VCAH100, and VCEH100. You will often replace it during regular maintenance or when rebuilding the pump.
The O-ring helps block air, oil, or dirt from leaking. This keeps the vacuum strong and the pump working properly. Buna is a good, affordable choice for everyday use in factories or labs. It is easy to install and helps your equipment last longer.
Many technicians keep this part on hand because it is a direct fit and fixes small sealing problems quickly.
