It measures 2.975 inches inside diameter and 3.375 inches outside diameter, with a thickness of 0.1875 inches (3\/16 inches). The compound carries a Shore A hardness rating of 70 and is manufactured from FDA-compliant silicone material, making it suitable for installations where food-grade or sanitary compliance is required. Licensed plumbers, pipefitters, and mechanical technicians typically install this o-ring in flanged connections, pump housings, and fluid handling assemblies.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for residential and commercial applications where exposure to wide temperature swings, dry heat, weather, and ozone is expected. Its silicone compound provides good dry heat resistance and weather and ozone resistance, though oil resistance is limited. Typical install scenarios include water treatment equipment, food processing lines, chemical handling systems, and HVAC fluid circuits where FDA-compliant sealing material is specified. Each package contains 5 o-rings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-compliant silicone material meets food-grade and sanitary application requirements\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range from -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore A hardness of 70 provides a firm, reliable seal under compression\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in limited concentrations\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent sealing contact in standard o-ring grooves\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 337 o-ring replacement for equipment using a 2.975-inch ID groove profile.

Depressurize and drain the system fully before removing the old o-ring. Lightly lubricate the o-ring with a compatible, FDA-approved lubricant before seating to prevent tearing during assembly. Do not use petroleum-based lubricants with silicone compound, as they may degrade the seal over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.975 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.375 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\u003eThickness (mm)\u003c\/strong\u003e: 5.33 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 337\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: Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Red\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: -80 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 450 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible With\u003c\/strong\u003e: Oils, Chemicals, Solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.235 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: ZMSCS70FDA337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717236883762,"sku":"ZMSCS70FDA337","price":19.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_bc9adeb5-9b85-4694-906a-d998684b3fa9.jpg?v=1788537239","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70fda337-o-ring-dash-337-silicone-fda","provider":"Voomi Supply","version":"1.0","type":"link"}
