O-ring, 2.1 x 1 mm - Viton, Part# 320210 - vacstellar
O-ring, 2.1 x 1 mm - Viton, Part# 320210 - vacstellar
This O-ring has an inside diameter of 2.1 mm and a thickness of 1 mm . That is a very small size. It is used in locations where larger seals cannot fit. It sits snugly in its groove. When you tighten the parts together, it compresses and creates a tight seal.
This O-ring is a direct replacement. It fits right into the groove. Because it is so small, you may want to use tweezers to place it carefully. No cutting or gluing is needed. Just place it in position and assemble the parts.
Choose this Viton O-ring for a reliable seal. It helps your Pfeiffer pump keep working the way it should

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 .
