ring Gasket, Rietschle, V-VC, Part# 704039 – vacstellar

This ring gasket is a small but important piece in Rietschle vacuum pumps. It is made from C-4401 material, which is tough and good at sealing flat or ring-shaped areas. Its job is to stop air, gases, or small leaks from happening inside the pump.

It fits several models in the V-VC family, such as VC200, VC300, VC400, VC500, VC700, VC202, and VC303. You often replace it during regular service, when fixing leaks, or as part of a bigger repair kit. A fresh gasket helps the pump hold vacuum better, run quieter, and avoid losing performance over time..

Shops and labs like to have this part ready. It may look basic, but it makes a big difference in how well the pump works day after day.
