Viton compound provides high resistance to petroleum-based fluids, wide chemical compatibility, low compression set, and a working temperature range of -15 degrees F to 400 degrees F. This makes it well suited for demanding sealing applications in HVAC, plumbing, and industrial fluid systems where standard Buna-N would degrade. Each order unit contains a package of 5 rings. Installation is performed by licensed or journeyman-level tradespeople or mechanical technicians.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in static or dynamic sealing applications where the media is petroleum-based fluid, fuel, hydraulic oil, or chemically aggressive fluid. The Viton compound is also rated for vacuum service and exhibits low gas permeability, making it appropriate for refrigerant-side sealing tasks and vacuum-hold checks during HVAC service. It is not FDA approved and is not intended for food-contact applications. The round cross section fits standard O-ring groove profiles machined to Dash 252 dimensional standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFluoroelastomer (Viton) compound resists petroleum products, fuels, and a wide spectrum of chemicals\u003c\/li\u003e\n\u003cli\u003eWorking temperature range of -15 degrees F to 400 degrees F\u003c\/li\u003e\n\u003cli\u003eLow compression set helps maintain long-term sealing force in static joints\u003c\/li\u003e\n\u003cli\u003eLow gas permeability and vacuum-service rated for refrigerant-side and pneumatic applications\u003c\/li\u003e\n\u003cli\u003eRound cross section fits standard Dash 252 groove geometry\u003c\/li\u003e\n\u003cli\u003eHardness rated 70 Shore A (Hard classification)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service-stock O-ring for any application requiring a Dash 252 dimensioned seal in fluoroelastomer, including petroleum fluid systems, hydraulic assemblies, and refrigerant-adjacent sealing points.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO-ring installation should be performed by a qualified HVAC technician, plumber, or mechanical technician. Always depressurize, drain, or pump down the system and shut off all energy sources before breaking any joint. Inspect the mating groove for burrs, corrosion, or debris before seating the ring, and apply a compatible lubricant to ease installation and reduce risk of nicking the seal. Do not twist or roll the ring during 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: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.5 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\u003eDash Number\u003c\/strong\u003e: 252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\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: ZMSCV70252\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721798615346,"sku":"ZMSCV70252","price":23.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f454c1f9de16ab9e6ff5ff584616218.jpg?v=1788581053","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70252-viton-o-ring-dash-252-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
