With a 4.625-inch inside diameter, 4.875-inch outside diameter, and a 0.125-inch round cross section, this O-ring fits large-bore sealing grooves common in industrial and mechanical assemblies. The 70 durometer hardness rating balances flexibility and compression resistance. Viton compound delivers low compression set, low gas permeability, and broad chemical compatibility. This package contains 5 O-rings. Licensed tradespeople and industrial maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for hydraulic systems, pneumatic assemblies, pump housings, valve bodies, and piping flanges that handle petroleum products, fuels, oils, and high-temperature process fluids. The fluoroelastomer compound performs reliably from -15 degrees F to 400 degrees F, making it appropriate for demanding service environments where standard Buna-N rings fail prematurely. It is also rated for vacuum service due to its low gas permeability, which extends its usefulness to vacuum pump sealing and low-pressure gas containment applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F continuous service\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness for firm sealing under pressure without excessive deformation\u003c\/li\u003e\n\u003cli\u003eLow gas permeability suitable for vacuum service and gas containment\u003c\/li\u003e\n\u003cli\u003eGood resistance to petroleum products, fuels, and a wide spectrum of chemicals\u003c\/li\u003e\n\u003cli\u003eLow compression set maintains seal integrity over extended service intervals\u003c\/li\u003e\n\u003cli\u003eRound cross section in Dash 247 standard sizing for drop-in replacement compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with systems and assemblies handling petroleum products, fuels, and high-temperature fluids where Dash 247 fluoroelastomer O-rings are specified.

Relieve all system pressure and drain fluid before disassembling any housing or valve body. Inspect the groove for nicks, burrs, or corrosion before seating the new O-ring; use only a compatible, petroleum-based or fluoroelastomer-safe lubricant to ease installation and prevent cutting the ring on sharp edges. Do not roll or twist the O-ring during installation, as this compromises the sealing surface.\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\u003eDash Number\u003c\/strong\u003e: 247\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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 durometer (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 Fluids\u003c\/strong\u003e: Petroleum products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Service Rated\u003c\/strong\u003e: Yes\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: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCV70247\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714610004274,"sku":"ZMSCV70247","price":20.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/510ab8dd5be73a97da76db56ff0072d3.jpg?v=1788503861","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70247-viton-o-ring-dash-247-pack-of-5","provider":"Voomi Supply","version":"1.0","type":"link"}
