Stepped seals are used to buffer pressure spikes from the primary rod seal, and are sometimes used in tandem. Combined with an unloaded U-cup, pressure builds between the step seal and primary seal and helps load the U-cup. Seals are machined from bronze filled PTFE. Expanders are 70 durometer high memory nitrile, also available with FKM expander rings. Part numbers that contain a P63D suffix are made from 63 shore D polyurethane.
