It measures 30 inches inside diameter, 36 inches outside diameter, and 3 inches thick with a round cross section. The compound carries a Shore A hardness of 75, placing it in the hard range, which helps maintain seal integrity under compression. Rated for service from -15 degrees F to 400 degrees F, this O-ring is a dependable choice wherever thermal cycling and petroleum-based fluid exposure are primary concerns.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for industrial sealing applications involving petroleum products, hydraulic fluids, and chemical process media. Its large diameter makes it appropriate for flanged connections, large-bore cylinder heads, tank covers, and similar heavy-equipment joints in industrial and manufacturing environments. Licensed plumbers, pipefitters, and millwrights working on large-diameter fluid systems are the typical installers. The fluoroelastomer formulation also supports vacuum service and delivers low gas permeability, extending its usefulness to pneumatic and vacuum system applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) material provides high temperature resistance up to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eRated to -15 degrees F for cold-temperature service\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 75 for reliable compression set resistance\u003c\/li\u003e\n\u003cli\u003eRound cross section for standard groove compatibility\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products and a wide spectrum of chemical media\u003c\/li\u003e\n\u003cli\u003eLow gas permeability suitable for vacuum service applications\u003c\/li\u003e\n\u003cli\u003eBlack color; non-FDA-approved formulation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation seal for large-diameter flanged and gasketed connections where fluoroelastomer O-rings with a 30-inch inside diameter are specified.

De-pressurize and drain the system fully before removing any existing seal or cover. Inspect the groove for scoring, corrosion, or debris before seating the O-ring; a damaged groove will compromise the seal regardless of O-ring condition. Do not use sharp tools to seat the ring, and avoid twisting or stretching beyond what is required for installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 36 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 (Shore A)\u003c\/strong\u003e: 75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCV3X30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697794810162,"sku":"ZMSCV3X30","price":26.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_b5918435-bf6c-45c8-9c16-ac58f1dd8c53.jpg?v=1788354374","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv3x30-viton-o-ring-30x36x3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
