With a 1-inch inner diameter and 1.5-inch outer diameter, this seal has a 0.375-inch thickness and is rated for operating temperatures from -20 degrees F to 250 degrees F. It is compatible with a 3\/8-inch pipe thread connection and is built to handle a maximum operating pressure of 2000 psi. Polypak seals of this type are typically installed by hydraulic technicians, maintenance mechanics, and industrial plumbers working on cylinders, actuators, and fluid power assemblies.\u003c\/p\u003e\n\u003cp\u003eThis seal fits applications where a compact, energized packing seal is needed to prevent fluid bypass in reciprocating or rotary equipment. The Polypak design uses a U-cup profile that self-energizes under system pressure, making it well suited for hydraulic cylinders, pneumatic actuators, and fluid control components found in industrial, commercial, and trade service environments. The 3\/8-inch pipe thread spec and defined dimensional envelope make this a direct-fit replacement in systems originally specced for this seal size and profile.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolypak U-cup seal profile self-energizes under system pressure for consistent sealing performance\u003c\/li\u003e\n  \u003cli\u003eRated to 2000 psi maximum operating pressure for demanding hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eTemperature range of -20 degrees F to 250 degrees F suits a wide range of fluid and ambient conditions\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch pipe thread compatibility for direct installation into threaded ports\u003c\/li\u003e\n  \u003cli\u003eCompact 1-inch ID by 1.5-inch OD by 0.375-inch thick envelope for drop-in fitment\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement Polypak seal for hydraulic cylinders, pneumatic actuators, and fluid power components requiring a 1-inch ID by 1.5-inch OD by 0.375-inch thick seal profile with 3\/8-inch pipe thread fitment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or mechanic. Depressurize and isolate the hydraulic or pneumatic circuit completely before disassembling any components to replace this seal. Inspect the mating bore and rod surfaces for scoring or damage before installing a new seal, as surface irregularities will shorten seal life. Lubricate the seal lightly with compatible system fluid during installation to prevent lip damage on assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Thickness\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 2000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -20 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Thread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Polypak Seal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 20122851\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 426325001000-375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539448889650,"sku":"426325001000-375","price":86.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6295cd8964363d0e352964c0d73c993a.jpg?v=1785840490","url":"https:\/\/voomisupply.com\/products\/parker-426325001000-375-polypak-seal-1in-id-1-5in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
