Constructed from Ethylene Propylene Diene Monomer (EPDM) rubber with a round cross section and a 70 Shore A hardness rating, this O-ring provides reliable sealing across a broad temperature range of -65 degrees F to 300 degrees F. It measures 4.625 inches inside diameter, 5.000 inches outside diameter, and 0.1875 inches (3\/16 inches) thick. Licensed tradespeople and maintenance technicians install these in systems handling hot water, steam, and phosphate ester hydraulic fluids. Sold in a package quantity of 12.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for commercial and industrial sealing applications where hot water, steam, or phosphate ester hydraulic fluids are present. It is specifically noted for excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it relevant for aerospace ground support and MRO environments. EPDM material also makes this a practical choice for plumbing, HVAC hydronic systems, and any application requiring consistent performance at elevated temperatures. The package quantity of 12 supports stocking and service kit assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM construction rated for service from -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for a firm, reliable seal under compression\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 350 standard sizing for consistent fitment\u003c\/li\u003e\n  \u003cli\u003eExcellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems\u003c\/li\u003e\n  \u003cli\u003eCompatible with hot water, steam, and phosphate ester type hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eSold in a package of 12 to support service stock and kit builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with systems handling hot water, steam, and phosphate ester type hydraulic fluids, including applications requiring resistance to Skydrol fluids in commercial aircraft hydraulic systems.

Inspect the seating groove for damage, debris, or corrosion before installing the new O-ring. Lubricate the O-ring with a fluid compatible with EPDM material to prevent tearing during assembly. Avoid using petroleum-based lubricants, as they are incompatible with EPDM and will cause degradation.\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: 350\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4.625 inches (4-5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/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 hydraulic fluids, Skydrol\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: 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: ZMSCE70350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723908055346,"sku":"ZMSCE70350","price":37.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_f175754c-80f9-423d-bcda-9944fbc636b3.jpg?v=1788609729","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70350-epdm-o-ring-dash-350-pack-12","provider":"Voomi Supply","version":"1.0","type":"link"}
