Encapsulated O-Rings - the Covering Makes the Difference

Elasticity with the greatest possible media resistance – encapsulated O-Rings offer outstanding functional reliability in demanding static sealing situations.

The combination of an elastomer O-Ring and a closed encapsulation made of modified PTFE makes encapsulated O-Rings from Superior Bearing and Supply an ideal sealing component for contact with aggressive media: with simultaneously high elastic behavior for an optimal contact pressure,the kind that only an elastomer can provide.

Depending on the temperature resistance needed, either FKM or VMQ is used as the core material. The encapsulation consists of FEP or PFA.

The range of application focuses exclusively on static sealing due to the encapsulation. Encapsulated O-Rings are available in nearly all desired sizes, inner diameters and ring thicknesses, in metric or imperial dimensions. Both the encapsulation and, if desired, the elastomer core are FDA-compliant.
