It carries a Dash 441 designation and a Shore hardness rating of 70 (Hard). Silicone construction gives this o-ring a wide serviceable temperature range from -80 degrees F to 450 degrees F, making it a practical choice for sealing applications that see significant thermal cycling or sustained elevated heat. It is sold individually and weighs 0.02 pounds. Plumbers, pipefitters, industrial maintenance technicians, and equipment service professionals commonly install this type of o-ring in static sealing applications across fluid and gas systems.\u003c\/p\u003e\n\u003cp\u003eThis o-ring is suited for use in applications requiring good dry heat resistance, weather resistance, and ozone resistance. It is rated for limited compatibility with oils and performs well with certain chemicals and solvents. Typical install scenarios include flanged connections, cap seals, and groove-seated static joints in industrial, HVAC, and plumbing equipment where large-diameter seals are needed. The white color and silicone material are common in food-adjacent and high-temperature industrial environments, though this specific o-ring is not FDA approved and should not be used in food-contact applications where FDA compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicone material provides a working temperature range of -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eDash 441 standard sizing: 7 inches ID, 7.5 inches OD, 0.25 inches thick\u003c\/li\u003e\n  \u003cli\u003eShore hardness of 70 (Hard) for firm, reliable sealing under compression\u003c\/li\u003e\n  \u003cli\u003eRound cross section for standard groove fitment\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance extends service life in exposed or outdoor equipment\u003c\/li\u003e\n  \u003cli\u003eCompatible with select chemicals and solvents; limited oil resistance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service seal for equipment requiring a Dash 441 silicone o-ring with a 7 inch inside diameter and round cross section.

Before replacing the o-ring, depressurize and drain the system or component being serviced to prevent fluid or gas release. Inspect the seating groove for nicks, corrosion, or debris before installing the new o-ring. Avoid using petroleum-based lubricants on silicone o-rings; use a silicone-compatible lubricant only if needed for assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 441\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: White\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 With\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited oil resistance)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\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: ZMSCS70441\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":67581053894962,"sku":"ZMSCS70441","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a266103dfb304c80170ac13e16410517.jpg?v=1790399275","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70441-silicone-o-ring-dash-441","provider":"Voomi Supply","version":"1.0","type":"link"}
