With an 8.6-inch inside diameter, 13.4-inch outside diameter, and 2.4-inch cross-section thickness, this ring seats into wide-bore grooves and flanged connections where a reliable, compression-set-resistant seal is required. Rated for service from -40 degrees F to 250 degrees F, it holds up across a broad thermal range. The 70 durometer hardness and round cross-section profile make it straightforward to seat and inspect. Plumbers, pipefitters, industrial maintenance techs, and HVAC mechanics working on large-bore assemblies are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use with petroleum-based fluids, hydraulic oils, fuels, and lubricants — the primary compatibility strength of Buna-N elastomers. Typical applications include large pump housings, hydraulic cylinder end caps, industrial valve bonnets, and flanged piping assemblies in commercial HVAC, plumbing, and light industrial environments. The black Buna-N compound is the most widely used O-ring elastomer in trade applications for exactly this kind of broad fluid compatibility. It is not suited for exposure to ozone, direct sunlight, or environments with ozone-generating electrical equipment during storage or service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (nitrile butadiene rubber) compound — excellent resistance to petroleum products, hydraulic fluids, and lubricating oils\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness rating provides a firm, stable seal with good tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile for consistent groove fill and reliable compression set performance\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in packages of 100 with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic oils, fuels, and lubricants.

Depressurize and fully drain the system before removing the old O-ring or installing a new one. Lightly lubricate the O-ring with a compatible fluid or grease during installation to prevent tearing during seating — do not use petroleum-incompatible lubricants. Inspect the groove for nicks, burrs, or corrosion before seating the ring to ensure a proper seal.\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\u003eInside Diameter\u003c\/strong\u003e: 8.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 13.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross-Section Thickness\u003c\/strong\u003e: 2.4 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 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\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\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: ZMSCH2.4X8.6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718353813810,"sku":"ZMSCH2.4X8.6","price":17.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_07797c9a-7df9-4745-9ba9-c9d903f34d15.jpg?v=1788552406","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch2-4x8-6-o-ring-8-6-in-id-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
