This Case Gasket (Part #300215) is made from high-quality cork. It sits between the main body parts of your Pfeiffer vacuum pump. Its job is simple but very important: it creates a tight seal. This seal stops air from leaking out and keeps dirt from getting in. A good gasket means your pump holds strong vacuum pressure. This specific gasket fits the Pfeiffer UNO 250A and DUO 250A models. If you notice oil sweating or leaking from the middle of your pump, this gasket may need to be replaced.
