Rod Seals

430 (dynamic glide ring, double acting)

Dynamic seal, primarily intended as a repair seal, for applications where an existing O-ring would fail due to extrusion. It can be incorporated into a standard O-ring groove due to its slender design.

The seal can also be used for new development, where groove depth has to be limited

Two-part composition, consisting of a dynamic glide ring and an O-ring.
