Parker 426325001500-375 Polypak Seal 1.5x2 in

Product Description

The PARKER 426325001500-375 is a Polypak seal designed for use in hydraulic and pneumatic systems requiring a reliable dynamic sealing solution. With an inner diameter of 1.5 inches, an outer diameter of 2 inches, and an axial thickness of 0.375 inches, this seal is engineered to maintain a pressure-tight fit in high-demand applications. It is rated for a maximum operating pressure of 2000 psi and performs across a temperature range of -20 to 275 degrees F. Hydraulic technicians and fluid power specialists install this type of seal during cylinder repair, pump servicing, or actuator maintenance where a low-profile, high-pressure lip seal is required.

This Polypak seal is suited for hydraulic cylinders, actuators, and fluid power components in both residential and commercial service environments. The U-cup style profile is commonly used in reciprocating rod and piston applications where consistent sealing under dynamic load is essential. It is appropriate for use in industrial machinery, mobile hydraulic equipment, and mechanical systems that operate within its rated pressure and temperature limits.

Key Features

• 1.5 inches inner diameter and 2 inches outer diameter for precise bore fitment
• 0.375 inches axial thickness for low-profile installation in tight seal grooves
• Rated to 2000 psi maximum operating pressure for high-demand hydraulic service
• Operating temperature range of -20 to 275 degrees F suits a broad range of fluid and ambient conditions
• Polypak profile provides consistent dynamic sealing in reciprocating applications

Compatibility

Designed as an OEM-style replacement Polypak seal for hydraulic cylinders and fluid power actuators requiring a 1.5 inches ID by 2 inches OD by 0.375 inches seal groove specification.

Installation Notes

Installation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and lock out the hydraulic system fully before disassembling any cylinder or actuator. Lubricate the seal with compatible hydraulic fluid before seating it in the groove to prevent lip damage during assembly. Avoid using sharp tools near the sealing lip, as nicks or cuts will cause immediate leakage under pressure.
