Molded from Ethylene Propylene Diene Monomer (EPDM) compound, this O-ring carries a Shore A hardness of 70 and a round cross-section profile. It measures 7.5 inches inside diameter, 7.688 inches outside diameter, and 0.094 inches thick. The material formulation provides broad chemical compatibility and a working temperature range of -65 degrees F to 300 degrees F, making it suitable for hot water, steam, and phosphate ester hydraulic fluid service. Each order contains a package of 4 O-rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial plumbing, hydronic heating systems, and industrial hydraulic assemblies where EPDM-compatible media are present. It performs well in hot water and steam service, and it is also recommended for use with phosphate ester type hydraulic fluids, including Skydrol fluids used in commercial aircraft hydraulic systems. Plumbers, HVAC technicians, and millwrights commonly specify this compound for sealing flanges, valve bodies, and pipe couplings operating within the stated temperature limits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEPDM compound rated from -65 degrees F to 300 degrees F working temperature range\u003c\/li\u003e\n\u003cli\u003eDash 169 standard sizing: 7.5 inches ID, 7.688 inches OD, 0.094 inches thick\u003c\/li\u003e\n\u003cli\u003eShore A hardness of 70 for reliable compression sealing\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile for consistent gland fit\u003c\/li\u003e\n\u003cli\u003eCompatible with hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n\u003cli\u003eSold in a package of 4 O-rings per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with hot water, steam, and phosphate ester type hydraulic fluid systems, including Skydrol hydraulic fluids used in commercial aircraft applications.

Inspect the gland and mating surfaces for nicks, burrs, or corrosion that could damage the new seal. Lubricate the O-ring with a compatible fluid or grease before installation to prevent pinching or twisting during assembly. Installation is typically performed by licensed plumbers, HVAC technicians, or qualified industrial mechanics following applicable IPC or system manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: EPDM (Ethylene Propylene Diene Monomer)\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\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\u003eShore A Hardness\u003c\/strong\u003e: 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 300 degrees F\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: 4\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: ZMSCE70169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51690419388722,"sku":"ZMSCE70169","price":17.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_97ada6cb-13fb-45d7-8ab5-fab0fc26871f.jpg?v=1788269968","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70169-epdm-o-ring-dash-169-4-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
