Busch Filter Kit – 0025/0040D KB Part# BFK005A

We put everything you need in one box. No running around looking for missing parts. Here is what you get :

Exhaust Filter with Silencer (130 mm length)
This is the main part. It traps oil mist and dirt before they leave the pump. The built-in silencer makes your pump run quieter too. This filter is 130 mm long and fits your pump perfectly .

Oil Filter
Clean oil is the lifeblood of your vacuum pump. This oil filter removes dirt and tiny metal particles from the oil. Clean oil means your pump will last much longer .

Cylinder Gasket
This flat gasket seals the pump cylinder. A good seal means no air leaks and better vacuum.

O-rings (2 pieces)
You get two Viton O-rings. Viton is a special rubber that handles high heat and chemicals. These small rings stop air leaks at key connection points.

Dowty Seal (Viton)
This is a metal-rubber washer. It seals the oil drain area tight. Made of Viton for long life .

Oil Drain Plug (Nylon)
A new plug for the oil drain hole. Old plugs can crack and leak. This new one keeps the oil inside where it belongs.

Oil Sight Glass
This lets you see how much oil is in the pump. You can also check if the oil looks dirty or milky. A clean sight glass makes maintenance easy .
