Sight Glass Gasket, Leybold, Trivac, D2.5E, D5E, Part# 300044 – vacstellar

This gasket is the seal that makes that window work properly. It sits between the sight glass lens and the pump body. Its job is simple but very important: it creates a perfect seal to stop oil from leaking out.

First, it keeps your work area clean and safe by preventing messy oil leaks. Second, it ensures your pump doesn’t lose the oil it needs to run smoothly and stay cool. If this gasket gets old, hard, or cracked, you might see oil seeping out, or the view through the glass could get cloudy.

This is the original, part designed for your pump. It replaces Leybold part number 300044. It is made to fit the sight glass on Trivac D2.5E and D5E pump models perfectly.

Replacing a worn sight glass gasket is a quick and easy maintenance task. It helps you maintain a clear view of your oil level and protects your pump from running low. Keep your system sealed and your view clear with this reliable gasket.
