Description
This ring gasket is a small but very important piece for your Leybold Trivac pump. It fits the D40BCS and D65BCS models perfectly.
These pumps work hard in labs, factories, and chemical processes. Over time, the old gasket can wear out and let tiny leaks happen. That means less vacuum power and more oil mess.
Our gasket is built to the exact same size and shape as the original Leybold part. It slips right into place during a filter change or quick service.
Once installed, it locks everything tight. No more air sneaking in. No more oil dripping out. Your pump goes back to pulling strong vacuum like it did when it was new.
It is tough enough for daily use and gentle on the pump parts. Many technicians keep a few extras on the shelf because they are so easy to swap and they last.
If your pump feels a bit sluggish or you notice oil spots near the exhaust filter, this is often the fix. Simple to install, even if you are not a pro. Just drain the oil, remove the old gasket, pop in the new one, and you are good to go.
Keep your Trivac running right with this reliable ring gasket.
