Flat Gasket- Leybold Trivac, Part# 20009780 – vacstellar

This flat gasket is a simple but essential part for your Leybold Trivac vacuum pump. It sits between flat surfaces inside the pump to stop oil, air, or dirt from leaking out. This helps the pump hold a steady vacuum and work without any mess or loss of power.

It is made to fit perfectly in the Leybold Trivac D40BCS and D65BCS models. You will often see it used during regular maintenance or when doing an oil filter service. Replacing this gasket at the right time keeps everything tight and prevents small problems from turning into bigger ones.

 It is easy to install and gives you peace of mind that your pump is sealed properly. Many technicians keep a few of these on hand because they are quick to swap and make a real difference in how well the pump performs over time.
