KB04

The KB04 profile is a modification of both the KB02 and KB03 profiles. The inclusion of the pressure activated back-up ring offers extrusion resistance and ensures safe use at higher pressures.

The use of the KB04 profile also allows the design engineer to use larger radial clearances where metal to metal contact must be avoided in applications that may have potential side-load/misalignment issues.

The O-Ring energizer offers increased sealing ability in low pressure or soft start systems where standard rod seals would allow low pressure fluid bypass.
