Description
The sight glass on your vacuum pump is more than just a window. It’s a vital diagnostic tool. A quick glance tells you if your pump has enough clean oil. Without enough oil, the internal parts—like the vanes and bearings—will grind against each other. This causes overheating, rapid wear, and can lead to a complete breakdown.
This Oil Sight Glass Gasket (Part #48027100) is the fix. It is a seal designed to fit perfectly around the sight glass of several popular pump series. Over time, the original rubber or fiber gasket can become hard, flattened, or cracked. It loses its ability to seal.
Installing a fresh, gasket restores that tight seal in minutes. It ensures your oil stays where it belongs and your vacuum remains strong.
