It measures 6 inches inside diameter, 6.5 inches outside diameter, and 0.25 inches thick, conforming to Dash 437 sizing. With a Shore A hardness of 70 (hard rating), this O-ring provides reliable compression sealing across a working temperature range of -65 degrees F to 300 degrees F. Licensed plumbers, pipefitters, and mechanical contractors install this type of seal in hot water, steam, and hydraulic fluid applications.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial plumbing and mechanical systems where hot water and steam exposure is common. It is also recommended for use with phosphate ester type hydraulic fluids and demonstrates excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Typical install scenarios include flanged pipe connections, pump housings, valve bodies, and pressure vessel covers where a large-diameter face seal is required. Each package contains 6 O-rings. This is not FDA-approved and should not be used in food-contact applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEPDM material provides strong resistance to hot water and steam service\u003c\/li\u003e\n  \u003cli\u003eCompatible with phosphate ester hydraulic fluids and Skydrol aerospace hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -65 degrees F to 300 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 for consistent compression and sealing performance\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard O-ring groove fitment\u003c\/li\u003e\n  \u003cli\u003eDash 437 designation for straightforward cross-referencing and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with hot water, steam, and phosphate ester hydraulic fluid systems.

Always depressurize and isolate the system before removing the old seal. Inspect the O-ring groove for scoring, corrosion, or dimensional damage before installing the new seal. Avoid using petroleum-based lubricants on EPDM O-rings; use a compatible silicone or water-based lubricant only.\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\u003eInside Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.5 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: 437\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore A Hardness\u003c\/strong\u003e: 70 (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: 6\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: ZMSCE70437\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701146255666,"sku":"ZMSCE70437","price":17.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_f130206b-d9af-402d-90de-965b58ee50ac.jpg?v=1788398809","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsce70437-epdm-o-ring-dash-437-pack-of-6","provider":"Voomi Supply","version":"1.0","type":"link"}
