Description
O-rings are simple rings that create a seal. They stop oil and air from leaking at connection points. But not all O-rings are the same.
The service block on your vacuum pump is a key area. It deals with hot oil and sometimes chemical vapors. A standard rubber O-ring can wear out quickly here.
This O-ring is special. It is made from Viton, a high-performance material.
Viton is much stronger than regular rubber. It stands up to high heat without cracking. It also resists swelling and damage from oil and chemicals.
Using this special O-ring in your service block means you get a seal you can trust. It will last longer and perform better under pressure.
This is the Busch replacement part. It is made to the exact size and material specification. It will fit perfectly and provide the protection your pump needs.
