With a 7.5-inch inside diameter, a 7.688-inch outside diameter, and a 0.094-inch round cross section, this O-ring is built for larger bore fittings and flanges. The fluoroelastomer compound delivers a hardness of 70 Shore A, providing low compression set and reliable sealing across a wide range of chemical exposures. Sold in packages of 2.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for HVAC, plumbing, hydraulic, and industrial fluid-handling applications where petroleum product resistance and high-temperature performance are required. It is appropriate for both vacuum service and pressurized systems. The broad chemical compatibility and low gas permeability make it a dependable choice for refrigerant-adjacent, fuel, and oil system sealing in residential and commercial installations. Licensed technicians and pipefitters typically source Dash 169 O-rings for larger valve bodies, manifold flanges, and pump housings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) material with 70 Shore A hardness for firm, reliable sealing\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -15 degrees F to 400 degrees F\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, fuels, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eLow compression set for long-term sealing integrity under sustained load\u003c\/li\u003e\n  \u003cli\u003eLow gas permeability — suitable for vacuum service applications\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard O-ring groove compatibility\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 systems requiring a Dash 169 fluoroelastomer seal with a 7.5-inch inside diameter.

Depressurize and isolate the system completely before removing the existing O-ring. Inspect the groove and mating surfaces for nicks or corrosion before seating the new O-ring. Use only a lubricant compatible with fluoroelastomer and the system fluid — do not use petroleum-based grease on O-rings unless confirmed compatible with the media being sealed.\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: 169\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.094 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\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  \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: ZMSCV70169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698256707890,"sku":"ZMSCV70169","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_4119512a-3d66-4bdb-8f6e-d35c258d20d1.jpg?v=1788360154","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70169-viton-o-ring-dash-169","provider":"Voomi Supply","version":"1.0","type":"link"}
