With a 6.25-inch inside diameter, 6.5-inch outside diameter, and a 0.125-inch round cross section, this O-ring is rated for continuous service from -15 degrees F to 400 degrees F. The 70-durometer hardness rating delivers low compression set and reliable sealing under sustained load. Sold in a package of two.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for use in HVAC, plumbing, pool, and industrial fluid systems where exposure to petroleum-based fluids, fuels, or elevated temperatures is a regular service condition. Fluoroelastomer construction provides broad chemical compatibility and low gas permeability, making it appropriate for vacuum service and pressurized fluid circuits. Plumbers, HVAC technicians, and industrial maintenance professionals commonly install this size in pump housings, valve bodies, flanged connections, and manifold assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) construction with 70-durometer hardness for low compression set and long service life\u003c\/li\u003e\n  \u003cli\u003eTemperature range of -15 degrees F to 400 degrees F for high-heat and refrigeration-adjacent applications\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, fuels, and a wide spectrum of chemical media\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability suitable for vacuum service and gas-handling circuits\u003c\/li\u003e\n  \u003cli\u003eRound cross section in standard Dash 259 sizing for drop-in replacement across grooved sealing surfaces\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of two units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 259 O-ring replacement compatible with grooved sealing surfaces calling for a 6.25-inch ID, 6.5-inch OD, 0.125-inch cross section fluoroelastomer seal in petroleum-fluid or high-temperature service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut off and depressurize the system before removing the old O-ring and inspect the groove and mating surface for scoring or corrosion prior to installation. Apply a thin film of a compatible lubricant to the O-ring before seating it to prevent twisting and tearing during assembly. Do not use petroleum-based grease unless confirmed compatible with the system fluid and the fluoroelastomer compound. Work follows applicable plumbing and mechanical codes including the IPC and relevant ASME sealing standards.\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: 259\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\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 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\u003eCompatible Media\u003c\/strong\u003e: Petroleum products and broad chemical spectrum\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: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCV70259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714494562610,"sku":"ZMSCV70259","price":15.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f725617a42d6f66049c8fa73d063a6b.jpg?v=1788502284","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70259-viton-o-ring-dash-259","provider":"Voomi Supply","version":"1.0","type":"link"}
