It measures 4 inches inside diameter, 8 inches outside diameter, and 2 inches thick. Rated at 70 Shore A hardness, this O-ring offers excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. It is installed by plumbers, pipefitters, hydraulic technicians, and mechanical maintenance professionals.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in applications involving petroleum products, oils, fuels, and hydraulic fluids in both residential and commercial or industrial settings. Its wide operating temperature range of -40 degrees F to 250 degrees F makes it appropriate for demanding environments. Buna-N is the most widely used O-ring elastomer in the trade, making this a common go-to for groove-seated seals in valves, pumps, fittings, and fluid-handling assemblies. The black color is standard for this material type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction — the most widely used O-ring elastomer in trade applications\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to petroleum products, oils, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eStrong compression set, tear resistance, and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section with 70 Shore A hardness rating\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 systems and assemblies using petroleum-based fluids, hydraulic oils, and fuels.

Always depressurize and de-energize the system before removing or installing sealing components. Inspect the groove for damage, burrs, or debris before seating the O-ring. Avoid twisting the O-ring during installation and use a compatible lubricant to prevent damage during assembly.\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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4 inches (4.00 mm as listed by manufacturer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8 inches (8.00 mm as listed by manufacturer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2 inches (2.00 mm as listed by manufacturer)\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 Fluids\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100\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: ZMSCH2X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716164387122,"sku":"ZMSCH2X4","price":15.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7017b2ba7152143db0355feddd6b447f.jpg?v=1788522645","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch2x4-o-ring-4in-id-8in-od-2in-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
