It measures 20 inches inside diameter, 26 inches outside diameter, and 3 inches thick. Rated for service from -40 degrees F to 250 degrees F, this O-ring delivers excellent compression set resistance along with strong tear and abrasion resistance. It is compatible with petroleum-based fluids and media, making it a standard choice for hydraulic, pneumatic, and fluid-handling systems across industrial and commercial trades. Hardness is rated at 70 Shore A (Hard).\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for static and dynamic sealing applications in hydraulic cylinders, pump housings, pipe flanges, valves, and fluid-transfer equipment where petroleum-product exposure is expected. Its large diameter makes it appropriate for industrial-scale equipment rather than residential plumbing fittings. Plumbers, pipefitters, millwrights, and industrial maintenance technicians are the primary installers. The part meets SAE and MIL-Spec standards, confirming its suitability for demanding service environments. It is sold in a package quantity of 50 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — excellent resistance to petroleum products\u003c\/li\u003e\n  \u003cli\u003eRound cross section, 3 inches thick, with consistent dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating for reliable compression set performance\u003c\/li\u003e\n  \u003cli\u003eTear and abrasion resistant for dynamic sealing applications\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum-based products and fluids.

Depressurize and drain the system completely before removing any existing seals or fittings. Lubricate the O-ring with a compatible petroleum-based lubricant during installation to reduce the risk of tearing or rolling. Do not store Buna-N O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades nitrile elastomers.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH3X20\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700183007538,"sku":"ZMSCH3X20","price":16.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4749761a189d6df445441ac2eba975f3.jpg?v=1788387299","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch3x20-o-ring-20in-id-26in-od-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
