AS2 - 2 PC STEPPED BTFE/NBR ROD BUFFER SEAL - METRIC

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 Teflon®. Expanders are 70 durometer high memory nitrile, and are also available in Viton. Part numbers that contain a P63D suffix are made from 63D shore urethane. Temperature: -40°F to 225°F Pressure: 0 to 3500 psi
