Lip seal

bondedelastomerNBR

Bonded seals are metal washers with a vulcanized trapezoidal elastomer sealing lip being used as static seals for screw connections and flange seals. By tightening the screw, the elastomer sealing lip is compressed and thus generates the sealing effect. The USS design includes a sealing lip that is formed to be self-centering. This ensures correct fitting and loss-free assembly automatically. Bonded seals of the Dichtomatik brand are available in standard steel and stainless steel, with an elastomer sealing lip made of NBR or FKM.
