Description
This assembly is a small window on the side of your pump. You simply look at it to see the oil inside.
Over time, the glass or seal can get dirty, scratched, or cloudy. It might even leak. When you can’t see through it, you’re guessing about your pump’s most important fluid. That’s a risk.
This part is a complete replacement assembly. It includes the clear glass and the metal housing. It is made to fit specific vacuum pump models. It replaces the old unit directly.
Installing a new sight glass restores your ability to perform quick, visual checks. This helps you maintain the correct oil level. It also lets you spot issues, like very dirty oil, early on.
It’s a simple part that makes maintenance safer, easier, and more reliable. No more unscrewing plugs just to check the oil.
