It carries a Dash 047 designation and a Shore hardness of 70, classifying it as a hard-durometer seal. Silicone compound gives this O-ring a wide service temperature range, from -80 degrees F to 450 degrees F, making it well suited for static sealing applications where dry heat resistance and weather stability are priorities. Licensed tradespeople in HVAC, plumbing, and industrial maintenance typically install this type of seal in flanged, grooved, or gasketed connections.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and light commercial applications where the sealed interface involves oils, chemicals, or solvents at moderate exposure levels. Its silicone material offers good weather and ozone resistance, though oil resistance is limited compared to Buna-N or Viton compounds. Typical install scenarios include replacement sealing on pump flanges, pipe unions, access covers, and similar static face-seal joints. This product is sold in a pack of 10, making it practical for service vehicles or stocking at a shop. It is not FDA approved and should not be used in food-contact or potable-water applications without verifying local code compliance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone compound rated for -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003eDash 047 standard sizing: 4.5 inches ID, 4.625 inches OD, 0.0625 inches thick\u003c\/li\u003e\n  \u003cli\u003eShore 70 hardness (hard durometer) for positive static sealing\u003c\/li\u003e\n  \u003cli\u003eRound cross section for compatibility with standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 units per order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 047 replacement O-ring for static sealing applications involving oils, chemicals, and solvents where wide temperature range and dry heat resistance are required.

Shut off and depressurize the system fully before removing the existing seal. Inspect the mating groove and seating surface for nicks, corrosion, or debris, and clean both surfaces before seating the new O-ring. Do not overstretch the O-ring during installation, and apply a compatible lubricant only if the application and fluid compatibility allow it.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\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: 047\u003c\/li\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: 4.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore (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\u003eCompatible Media\u003c\/strong\u003e: Oils, Chemicals, Solvents\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\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\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: ZMSCS70047\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720421179698,"sku":"ZMSCS70047","price":15.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b924c4d2d428b658d66e5c0b0b71173f.jpg?v=1788563716","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70047-silicone-o-ring-dash-047","provider":"Voomi Supply","version":"1.0","type":"link"}
