Our KB03A profile is an asymmetric single acting / uni-directional hydraulic piston u-cup seal complete with both an O-Ring energizer and multiple sealing lips. The O-Ring energiser helps sealing at low pressures, while the multiple sealing lips provide some sealing redundancy and lubrication reservoirs to help reduce friction in dynamic applications.

This seal has been used with great success as a replacement for static O-Rings that may see occasional dynamic movement and can be manufactured to suit most internationally recognised O-Ring groove sizes.

It is available in several of DMR’s high performance materials to provide increased extrusion resistance, low compression set and outstanding wear prorerties.
