Made from Ethylene Propylene Diene Monomer (EPDM) compound with a 70 durometer hardness rating, this O-ring is built for sealing applications that involve hot water, steam, and phosphate ester hydraulic fluids. It ships in a package of 9 rings. Licensed plumbers, HVAC technicians, and hydraulic system mechanics install this type of seal in fluid handling and pressure systems requiring reliable static or low-motion dynamic sealing.\u003c\/p\u003e\u003cp\u003eThis O-ring suits applications in plumbing, HVAC hydronic systems, and industrial fluid circuits where EPDM compatibility is required. EPDM material performs across a wide temperature range, from -65 degrees F to 300 degrees F, making it appropriate for both hot-water heating systems and steam service. It is also noted for resistance to Skydrol fluids used in commercial aircraft hydraulic systems and is recommended for phosphate ester type hydraulic fluids. This ring is not suited for petroleum-based oils or fuels despite a listed compatible material notation in the spec data.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eEPDM compound with 70 durometer hardness for firm, reliable sealing\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -65 degrees F minimum to 300 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eResistant to Skydrol hydraulic fluids used in commercial aircraft applications\u003c\/li\u003e\n\u003cli\u003eSuitable for hot water, steam, and phosphate ester hydraulic fluid service\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 427 standard sizing for drop-in replacement use\u003c\/li\u003e\n\u003cli\u003eSold in a package of 9 rings per order quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Dash 427 standard O-ring replacement for systems requiring EPDM seals in hot water, steam, hydronic heating, and phosphate ester hydraulic fluid service.

Clean the groove surface of any debris or residue from the previous ring before seating the new O-ring. Do not use petroleum-based lubricants with EPDM seals; use a compatible water-based or silicone-based lubricant if needed for installation. Follow applicable codes such as ASME B31 or IFGC for pressure and gas systems when replacing seals in those circuits.\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\u003eInside Diameter\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 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: 427\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: -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\u003ePackage Quantity\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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: ZMSCE70427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714387542322,"sku":"ZMSCE70427","price":19.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_7037fea5-2d1f-4115-8a76-1b9d03b04127.jpg?v=1788500712","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70427-epdm-o-ring-dash-427-9-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
