KB02B

The KB02B profile is an asymmetric single acting / uni-directional hydraulic piston working u-cup seal which is designed to help reduce the frictional footprint of the seal in dynamic applications via the inclusion of a secondary PTFE sealing element within the back heel of the main seal body.

Like other asymmetric seals the KB02B has an interference fit along its inside diameter to ensure a stable fit in the housing and to provide a tight leak free static seal across the inside diameter. The inclusion of the secondary PTFE sealing ring not only provides another sealing edge, but it also acts as a lubrication reservoir helping to reduce friction and help reduce the chance of stick-slip.
