It measures 4 inches inside diameter, 4.125 inches outside diameter, and 0.0625 inches thick. With a Shore A hardness rating of 70 (Hard), this O-ring maintains its seal across a wide service temperature range of -65 degrees F to 300 degrees F. Sold in a pack of 10, it suits shops and field techs who need spares on hand for recurring maintenance. Licensed plumbers, HVAC technicians, and hydraulic system mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving hot water lines, steam service, and phosphate ester type hydraulic fluids. It also carries a notable resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it useful across industrial and aviation-adjacent maintenance environments. The EPDM compound performs reliably in steam and hot-water distribution systems, expansion tank connections, and valve packing applications where synthetic rubber compatibility is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM compound rated for hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 (Hard) for consistent compression and sealing force\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 045 sizing for standard groove fitment\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 to support stock replenishment and field kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with hot water, steam, and phosphate ester type hydraulic fluid systems.

Lubricate the O-ring with a fluid compatible with EPDM before seating it in the groove to prevent tearing during assembly. Plumbing work on steam or hot-water systems must comply with applicable local codes and ASME guidelines. Do not use petroleum-based lubricants with EPDM O-rings, as they will cause the compound to swell and fail prematurely.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 045\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.125 inches (4.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches (1\/16 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\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\u003eCompatible Fluids\u003c\/strong\u003e: Hot Water, Steam, Phosphate Ester\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: 10\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: ZMSCE70045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720845820210,"sku":"ZMSCE70045","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ff70e82ab85fd4676d829394ba76c6b.jpg?v=1788569869","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70045-epdm-o-ring-dash-045-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
