With an inside diameter of 2.125 inches, an outside diameter of 2.5 inches, and a thickness of 0.1875 inches, this seal provides a reliable compression fit in standard gland installations. It is rated for a maximum operating pressure of 2000 psi and handles a temperature range of -20 to 250 degrees F, making it suitable for a broad range of fluid power and industrial service environments. Installation is typically performed by hydraulic technicians and maintenance mechanics working on cylinders, actuators, and similar components.\u003c\/p\u003e\u003cp\u003eThis Polypak seal is used in hydraulic cylinders, pneumatic actuators, and fluid power assemblies where a low-profile, energized lip seal is required. The 3\/8 pipe thread reference indicates compatibility with corresponding bore and gland configurations. It is well-suited for both light industrial and heavy-duty applications that demand consistent sealing performance across a wide operating temperature range. The compact cross-section allows installation in tight gland spaces common in mobile and stationary hydraulic equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.125 inches ID x 2.5 inches OD with 0.1875 inch thickness for precise gland fit\u003c\/li\u003e\n\u003cli\u003eRated to 2000 psi maximum operating pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -20 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003ePolypak energized lip design provides reliable dynamic sealing\u003c\/li\u003e\n\u003cli\u003eCompatible with 3\/8 pipe thread gland configurations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement Polypak seal for hydraulic cylinders and pneumatic actuators requiring a 2.125 inch ID seal with a 2000 psi pressure rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic or mechanical technician. Depressurize and isolate the hydraulic or pneumatic circuit completely before disassembling the gland. Inspect the gland bore and rod surface for wear or scoring that could compromise the new seal. Lubricate the seal lightly with system fluid during installation to prevent damage to the lip during assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Thickness\u003c\/strong\u003e: 0.1875 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\u003eTemperature Range\u003c\/strong\u003e: -20 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Thread\u003c\/strong\u003e: 3\/8 inch\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 426318702125-375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541736554802,"sku":"426318702125-375","price":115.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/807db24b8a4578c07ef5092afc8cb26f.jpg?v=1785883501","url":"https:\/\/voomisupply.com\/products\/parker-426318702125-375-polypak-seal-2-125-id-2-5-od","provider":"Voomi Supply","version":"1.0","type":"link"}
