DMR Seals KB01B profile is an asymmetric single acting/uni-directional hydraulic piston u-cup seal.
The seal has sharp dynamic sealing lips which help provide positive fluid film removal from the cylinder bore. The outer sealing lip has also been reduced in length to provide 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.
