Measuring 4.875 inches inside diameter, 5.125 inches outside diameter, and 0.125 inches thick, this round cross-section O-ring carries a Shore A hardness rating of 70. It is rated for continuous service from -15 degrees F to 400 degrees F, making it suitable for demanding fluid and gas sealing environments. Each order contains a pack of 5 O-rings. HVAC technicians, plumbers, and industrial service professionals commonly install this size in large-bore fittings, valve bodies, and pump flanges.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum-based fluids, hydraulic systems, fuel lines, and high-temperature sealing points. Its fluoroelastomer compound provides low gas permeability, making it appropriate for vacuum service as well. Installers working on large-diameter valve assemblies, compressor housings, or pump bodies will find this Dash 249 size a standard replacement geometry. The black color and round cross-section conform to industry-standard O-ring groove dimensions for Dash 249 profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) material with good resistance to petroleum products and fuels\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for a firm, low-compression-set seal\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability makes this ring suitable for vacuum service\u003c\/li\u003e\n  \u003cli\u003eRound cross-section conforms to standard Dash 249 O-ring groove dimensions\u003c\/li\u003e\n  \u003cli\u003ePack of 5 units per order with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service O-ring for any application requiring a standard Dash 249 O-ring with a fluoroelastomer compound rated for petroleum product contact and elevated temperatures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. Always depressurize and drain the system before removing or installing O-rings, and verify the mating groove dimensions match the Dash 249 profile before installation. Lightly lubricate the O-ring with a compatible fluid or grease prior to seating to prevent rolling or tearing during assembly. Do not use petroleum-incompatible lubricants with this fluoroelastomer compound.\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: 249\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.125 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\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\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: ZMSCV70249\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690683466034,"sku":"ZMSCV70249","price":19.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f1ae44382b22f5c99115bff4b9b79c9.jpg?v=1788273894","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70249-viton-o-ring-dash-249-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
