Washer, Orifice-Leybold Trivac, Part# 420032 – vacstellar

An Orifice Washer looks like a small, flat metal ring with a hole in the center.  It is a sized and calibrated opening. Its job is to control the rate at which air or oil can pass through a specific point in your pump. 

This little washer acts like a tiny traffic controller. It makes sure that just the right amount of flow goes where it needs to. This helps the pump run smoothly, maintain a strong vacuum, and operate at the correct temperature.

If this washer is missing, damaged, or replaced with an incorrect part, the flow can become unbalanced. This might cause the pump to perform poorly, use too much oil, or not pull a proper vacuum.

Using this Leybold part (Part# 420032, also called L0271) guarantees you have the right “traffic controller” for your system.
