With a 3-inch inner diameter, 3.5-inch outer diameter, and a seal thickness of 0.375 inches, this part provides a pressure-rated sealing surface rated to 2000 psi. The operating temperature range spans -20 degrees F to 250 degrees F, making it suitable for a wide range of industrial and mobile hydraulic service conditions. Licensed hydraulic technicians and fluid-power mechanics install this type of seal during cylinder rebuilds or scheduled maintenance intervals.\u003c\/p\u003e\n\u003cp\u003ePolypak seals are commonly used as rod seals in hydraulic cylinders found in industrial machinery, mobile equipment, and fluid-power systems. The 3\/8 pipe thread specification indicates this seal is dimensioned for use with standard pipe-thread porting configurations. The seal is sold individually and ships as a single-piece package, consistent with low-volume service and repair work where one cylinder end is being rebuilt at a time.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-inch inner diameter and 3.5-inch outer diameter for precise cylinder bore fitment\u003c\/li\u003e\n  \u003cli\u003eSeal thickness of 0.375 inches for consistent groove seating\u003c\/li\u003e\n  \u003cli\u003eMaximum operating pressure rated at 2000 psi\u003c\/li\u003e\n  \u003cli\u003eTemperature range of -20 degrees F to 250 degrees F suits diverse hydraulic fluids and environments\u003c\/li\u003e\n  \u003cli\u003e3\/8 pipe thread compatibility for standard porting configurations\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging supports individual cylinder service and rebuild work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement Polypak rod seal for hydraulic cylinders requiring a 3-inch ID by 3.5-inch OD by 0.375-inch thick seal profile rated to 2000 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHydraulic system technicians and fluid-power mechanics should depressurize and fully bleed the hydraulic circuit before removing any cylinder end caps or rod glands. Inspect the rod and cylinder bore for scoring or contamination before installing the new seal. Use appropriate seal installation tools to avoid cutting or rolling the seal lip during installation.
