14 x 14.945 x .32 Stepped BTFE 2Pc Rod Buffer Seal Assembly Inch

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.
