O-Ring,FKM – Part No.#48652600 – vacstellar

Description

O-rings are simple but critical seals. They sit in a groove between two parts. When the parts are fastened together, the O-ring compresses. This creates a leak-proof barrier.

A good O-ring keeps the vacuum strong. A worn or damaged O-ring lets air sneak in. This makes your pump work harder and less efficiently.This Busch O-ring is made from FKM. This is a special synthetic rubber. You might also hear it called Viton. It’s chosen for its superior properties in tough environments.
