Measuring 4.5 inches inside diameter, 4.75 inches outside diameter, and 0.125 inches thick, this round cross-section ring delivers a reliable seal in demanding service environments. With a Shore A hardness of 70 and a working temperature range of -15 degrees F to 400 degrees F, it is suited for high-heat systems including hydraulic circuits, fuel systems, and HVAC refrigerant or oil-side connections. Each package contains 5 rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is commonly installed in residential and commercial HVAC equipment, plumbing systems, fuel-handling assemblies, and industrial hydraulic applications wherever a 4.5-inch ID groove is specified. Its fluoroelastomer compound makes it a preferred choice over standard Buna-N rings when service conditions involve elevated temperatures, petroleum-based fluids, or vacuum service. Licensed HVAC technicians, plumbers, and millwrights typically install this ring as part of a seal kit replacement or scheduled maintenance service.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound offers wide-spectrum chemical compatibility including petroleum products\u003c\/li\u003e\n  \u003cli\u003eWorking temperature range of -15 degrees F to 400 degrees F for high-heat applications\u003c\/li\u003e\n  \u003cli\u003eLow compression set helps maintain seal integrity over extended service intervals\u003c\/li\u003e\n  \u003cli\u003eSuitable for vacuum service with low gas permeability\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile fits standard Dash 246 O-ring grooves\u003c\/li\u003e\n  \u003cli\u003ePack of 5 rings per package, minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 246 O-ring replacement for any application requiring a 4.5-inch ID fluoroelastomer seal.

Always depressurize, de-energize, and drain the system before removing the old O-ring or installing a replacement. Inspect the groove for nicks or debris, and apply a compatible lubricant to the O-ring before seating it to prevent tearing during assembly. Do not stretch the ring beyond what is necessary to seat it in the groove.\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\u003eDash Number\u003c\/strong\u003e: 246\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.75 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\u003eShore A Hardness\u003c\/strong\u003e: 70 (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\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\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: ZMSCV70246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718660161842,"sku":"ZMSCV70246","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dbe526ac06018718cc483af8f3b05918.jpg?v=1788554843","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70246-viton-o-ring-dash-246-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
