Viton compound delivers high-temperature resistance up to 400 degrees F, low compression set, and broad chemical compatibility — including strong resistance to petroleum products and low gas permeability. Rated at 70 durometer (hard), this O-ring suits demanding sealing applications where standard nitrile or EPDM compounds fall short. Licensed HVAC techs, plumbers, and industrial mechanics install this type of seal in pumps, valves, flanges, and fluid-system components requiring reliable static or dynamic face sealing.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is well suited for use in residential and commercial fluid-handling systems, including HVAC refrigeration circuits, petroleum-based fluid lines, vacuum service equipment, and hydraulic assemblies. The fluoroelastomer material handles aggressive media and sustained elevated temperatures that standard rubber compounds cannot tolerate. It is sold in a package quantity of two rings per order, making it practical for service calls that require a spare on hand. Install scenarios typically involve pump seal replacement, valve body seating, or flange face sealing in high-temperature or chemically aggressive environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) construction — rated for service from -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 durometer hardness for reduced extrusion risk under pressure\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, hydraulic fluids, and a wide spectrum of chemicals\u003c\/li\u003e\n  \u003cli\u003eLow compression set maintains sealing force over extended service intervals\u003c\/li\u003e\n  \u003cli\u003eSuitable for vacuum service applications with low gas permeability\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 253 standard sizing for consistent fit in standard O-ring grooves\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 Dash 253 standard-size seal in fluoroelastomer material, including pumps, valves, flanges, and fluid-system components compatible with Viton compound. Compatible media include petroleum products and other fluids within the chemical resistance range of fluoroelastomer. Not FDA approved — confirm media compatibility before use in food-contact or potable-water systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. De-energize equipment and relieve all system pressure before removing the old seal. Clean the O-ring groove thoroughly and inspect for scoring or corrosion before seating the new ring. Lubricate the O-ring with a compatible lubricant — confirm lubricant compatibility with fluoroelastomer and the system media before use.\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: 253\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.625 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 Media\u003c\/strong\u003e: Petroleum products and chemically compatible fluids\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: 2 rings\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: ZMSCV70253\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723232477490,"sku":"ZMSCV70253","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47c10cbfda5829da082474877448b443.jpg?v=1788602121","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70253-viton-o-ring-dash-253","provider":"Voomi Supply","version":"1.0","type":"link"}
