The KB03 profile is an asymmetric single acting / uni-directional hydraulic piston working u-cup seal complete with an O-Ring energiser which is recommended for low pressure or soft start systems. The O-Ring provides further sealing force across the sealing lips to ensure tight leak free performance even at low or zero pressure. The seal has a shortened dynamic lip for improved low friction sealing and compression set characteristics in comparison to standard symmetrical u-rings and has an interference fit along the inside diameter to ensure a stable fit in the housing and to provide a tight leak free static seal.

This seal is available in several of DMR’s high performance materials to provide the designer or repairer with exceptional extrusion resistance, low compression set and outstanding wear properties.
