63 x 53 x 7.5 4 Pc Heavy Duty BTFE/NBR/POM Piston Seal Assembly Metric

These heavy-duty seals are designed to withstand higher pressures and shock loads with less damage to the seal. T-seal principles are utilized with back-ups being used to protect the seal from contaminants. The compact design allows use of shorter pistons and larger bearing surfaces. 4 pc. piston seals come in many sizes to fit different types of equipment. 4PMMH Parts use a Hytrel® Piston Seal. 4PMMU Parts use a Urethane Piston Seal.
