Busch Exhaust Cover Gasket, End Part# 300068 – vacstellar

This gasket is a simple but vital part. It sits between the exhaust cover and the main pump body. When you tighten the cover, this gasket squashes down to form a perfect seal.

This seal does two important jobs. First, it stops air from leaking out. This lets your pump build and maintain a strong vacuum. Second, it keeps oil and dust from getting in where they shouldn’t.

This is the Busch part (300068). It is made to fit R5 series pumps like the 0165D, 0205D, 0255, 0255D, and 0305D exactly. The right fit means no leaks and no problems.

Made from durable material, it handles heat and pressure. Replacing a worn-out gasket is a quick fix that makes a big difference.
