It measures 4.5 inches inside diameter, 4.875 inches outside diameter, and 0.1875 inches thick. The compound is Ethylene Propylene Diene Monomer, which provides strong resistance to hot water, steam, and phosphate ester hydraulic fluids. Hardness is rated at 70 Shore A, placing it in the hard durometer range. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics are the typical installers for this size O-ring.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing connections, hydronic heating systems, and hydraulic systems using phosphate ester fluids. It is also recommended for use in commercial aircraft hydraulic systems where resistance to Skydrol fluids is required. The EPDM material performs across a wide service temperature range, making it appropriate for both low-temperature and elevated-temperature sealing environments. Sold in packages of 12, it is practical for shops and service vehicles that need to stock common sealing sizes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM compound delivers excellent resistance to hot water, steam, and phosphate ester hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eRated for service temperatures from -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness provides firm, reliable compression sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard O-ring groove compatibility\u003c\/li\u003e\n  \u003cli\u003eRecommended for Skydrol fluid environments in commercial aircraft hydraulic systems\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 12 supports stocking for recurring service work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with hot water, steam, and phosphate ester hydraulic fluid systems.

Always depressurize and drain the line or system before replacing any O-ring. Inspect the mating groove and sealing surfaces for damage, corrosion, or debris before seating the new ring. Apply a compatible lubricant to ease installation and prevent rolling or tearing of the O-ring during assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 349\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: EPDM (Ethylene Propylene Diene Monomer)\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\u003eColor\u003c\/strong\u003e: Black\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 hydraulic fluids, Skydrol\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: 12\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: ZMSCE70349\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691203821874,"sku":"ZMSCE70349","price":16.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_e1ddf3d6-36ea-4d03-b7ff-b4549018dcdc.jpg?v=1788281481","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70349-epdm-o-ring-dash-349-70-duro","provider":"Voomi Supply","version":"1.0","type":"link"}
