Ring Gasket, Rietschle, Part# 510581 – vacstellar

This ring gasket is a small but important part for many Rietschle vacuum pumps. It is made from Viton, a strong rubber material that handles heat, oil, and chemicals without breaking down easily. The ring shape helps it fit snugly in the right spot to block air or oil from leaking.

It works with a wide range of Rietschle pumps in the V-VC and V-VCA-VCE families. This includes models such as VCA25, VCE25, VCA40, VCE40, VCA60, VCE60, VC200, VCAH100, VCEH100, VC300, VC400, VC500, and VC700. You will often replace it during regular maintenance or when rebuilding the pump.

A fresh gasket keeps the pump sealed properly so it can hold a strong vacuum and run smoothly. It is straightforward to install and gives you confidence that everything is tight. Technicians like having this part ready because it is a direct fit and helps avoid bigger problems down the line.
