This Cork Case Gasket (Part #194081) is made specifically for the Pfeiffer DUO 2.5 vacuum pump. It goes between the two main halves of the pump body. Its job is to create a tight, reliable seal. This stops oil from leaking out. It also stops air from leaking in. A good seal means your pump holds strong vacuum pressure. If you are opening the pump for maintenance or a minor repair, you must replace this gasket. It is a one-time-use part .

Case Gasket, Cork, Pfeiffer, DUO, DUO2.5, Part# 194081
This is a flat, sheet-like gasket made from cork. Its part number is 194081. You place it between the two main halves of the pump’s outer body, also called the “case” . Think of it like the rubber seal on a jar lid. Without it, the jar would not stay closed tightly. With it, everything stays sealed and secure.
Cork is a smart choice for this type of gasket.
It compresses well: Cork squishes down easily. This lets it fill tiny gaps and scratches on the metal surfaces.
It resists oil: Cork does not break down or dissolve when it touches vacuum pump oil.
It is flexible: The cork can handle small movements and vibrations without breaking the seal.
