DMR Seals KB01A profile is an asymmetric single acting/uni-directional hydraulic piston working u-cup seal.

The seal has a shortened dynamic sealing lip and increased groove depth and groove width which offers increased seal deflection while providing improved friction and compression set characteristics in comparison to standard symmetrical u-rings.

It has an interference fit along the inside diameter to ensure a stable fit in the housing and to provide a tight static seal across the inside diameter of the seal groove.

This profile is available in several of our high-performance seal materials to provide both design engineers or repairers with exceptional extrusion resistance, low compression set and outstanding wear properties.
