Measuring 18 inches inside diameter, 23 inches outside diameter, and 2.5 inches thick, this round-cross-section ring provides a reliable static or dynamic seal where standard rubber would fail. A 75 Shore A hardness rating puts it in the hard range, reducing compression set under sustained load. Rated from -15 degrees F to 400 degrees F, it holds up in both cold-ambient and high-temperature service environments. Plumbers, pipefitters, and industrial maintenance technicians install this ring wherever chemical and thermal resistance are critical.\u003c\/p\u003e\n\u003cp\u003eThis O-ring suits large-bore flanged connections, valve bonnets, pump housings, and pressure vessel covers in commercial and industrial settings. Its fluoroelastomer compound is compatible with petroleum products, hydraulic fluids, and a wide spectrum of chemical media, making it appropriate for fuel systems, process piping, and vacuum service applications. The low gas permeability characteristic is especially useful in vacuum or low-leakage gas-handling assemblies. Package quantity is 10 rings per package with a minimum order quantity of 1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound rated to 400 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003eHard 75 Shore A durometer for low compression set under sustained clamping load\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products and a wide range of chemical media\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes it suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section for predictable sealing in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eBlack color; sold in packages of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard round-cross-section O-ring for large-bore industrial sealing applications compatible with petroleum products and systems requiring high-temperature fluoroelastomer seals.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed pipefitters, plumbers, or qualified industrial maintenance technicians. Depressurize and isolate the system completely before removing the existing seal and seating the new O-ring. Inspect the groove for burrs, corrosion, or dimensional damage before installation. Do not use petroleum-based lubricants with non-petroleum-compatible sealing surfaces; confirm lubricant compatibility with the system media before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 23 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2.5 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: 75 Shore A (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 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\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: ZMSCV2.5X18\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":52122498072882,"sku":"ZMSCV2.5X18","price":17.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_f64bb196-b8e2-485e-b8f3-9cfc1124ddf0.jpg?v=1790085372","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv2-5x18-viton-o-ring-18-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
