It measures 1 inch inside diameter by 1-1\/4 inch outside diameter with a 1\/8 inch thickness and is rated for operating temperatures from -20 degrees F to 250 degrees F. The seal handles a maximum operating pressure of 2000 psi, making it suitable for demanding fluid power applications. It installs as a rod or piston seal in hydraulic cylinders and actuators and is typically fitted by hydraulic system technicians or maintenance professionals working on industrial or mobile equipment.\u003c\/p\u003e\n\u003cp\u003eThis Polypak seal is used in hydraulic cylinders, pneumatic actuators, and fluid power assemblies where a compact, energized lip seal is needed to prevent fluid bypass. Its low-profile design suits tight gland configurations in both industrial machinery and mobile hydraulic equipment. The 1\/4 pipe thread reference in the product data indicates compatibility with standard ported housings of that thread size. Applications span industrial maintenance, OEM hydraulic cylinder builds, and field repair of actuators operating within the stated pressure and temperature range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 2000 psi maximum operating pressure for reliable performance in high-pressure hydraulic circuits\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -20 degrees F to 250 degrees F suits diverse operating environments\u003c\/li\u003e\n  \u003cli\u003e1 inch ID by 1-1\/4 inch OD profile fits standard hydraulic cylinder gland dimensions\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch seal thickness allows installation in compact gland designs\u003c\/li\u003e\n  \u003cli\u003ePolypak lip-seal design provides low breakout friction and consistent dynamic sealing\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement without excess inventory\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 and actuators requiring a 1 inch ID by 1-1\/4 inch OD seal with a 1\/8 inch thickness and a 1\/4 pipe thread housing configuration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hydraulic system technicians or qualified maintenance personnel. Depressurize and isolate the hydraulic circuit fully before disassembling any cylinder or actuator. Lubricate the seal lip with clean system fluid before installation to prevent damage during initial startup. Avoid using sharp tools near the sealing lip, as nicks or cuts will cause immediate leakage under pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Thickness\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Pressure\u003c\/strong\u003e: 2000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -20 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Reference\u003c\/strong\u003e: 1\/4 pipe thread\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 426312501000-250\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542905094450,"sku":"426312501000-250","price":76.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bb597d046dba258517fb825c8c2c239.jpg?v=1785910494","url":"https:\/\/voomisupply.com\/products\/parker-426312501000-250-polypak-seal-1in-id-1-1-4in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
