4PE/4PV - 4 PC BTFE or URE/NBR/NYLON PISTON SEAL - INCH

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. They are commonly found in Caterpillar® cylinders. Temperature: -40° to 225°F Pressure: 0 to 6,000 PSI
