- Two spring-loaded sealing lips
- Metal OD
Special features
- Separation of two media by just one seal
- Combination of 2 sealing lips in one component
- Very fi rm and exact fi t inside the housing due to metal-metal interference fit
- Be careful when using the product in connection with light metal housings, housings with increased surface roughness and applications with overpressure: Apply sealing aid to the outside diameter if necessary. A version with outside diameter coated with bore sealant is available on request.
