It measures 1.421 inches inside diameter, 1.687 inches outside diameter, and 0.125 inches thick, conforming to Dash 221 sizing. Made from FDA-compliant red silicone with a Shore hardness of 70, this O-ring is engineered for applications that demand a wide service temperature range and reliable sealing performance. It is commonly specified by plumbers, HVAC technicians, and equipment maintenance professionals in food-grade or high-temperature environments where standard nitrile or EPDM materials fall short.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications that require broad temperature tolerance and resistance to dry heat, weathering, and ozone exposure. FDA-compliant material makes it appropriate for food processing equipment, potable water systems, and sanitary plumbing assemblies. Its limited oil resistance means it is best reserved for dry-heat, steam, or water-contact service rather than petroleum-fluid systems. The 25-piece package quantity supports service kit stocking and multi-unit repair jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFDA-compliant red silicone material suitable for food-contact and potable water applications\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range of -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eShore hardness of 70 for 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\u003eRound cross section, Dash 221 standard sizing for straightforward replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package to support stocking and multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 221 O-ring replacement for equipment requiring FDA-compliant silicone seals in high-temperature or food-grade service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or equipment maintenance technicians. Always depressurize and isolate the system before removing the existing O-ring. Inspect the groove for scoring or debris before seating the new O-ring. Avoid using petroleum-based lubricants with silicone O-rings in food-grade or potable water service; use an appropriate silicone-safe or NSF-listed lubricant if needed.\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\u003eColor\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.421 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.687 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches (3.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore Hardness\u003c\/strong\u003e: 70 (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\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.41 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: ZMSCS70FDA221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696886743346,"sku":"ZMSCS70FDA221","price":22.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_56b885ac-f23b-483e-a9d2-e66f9b981469.jpg?v=1788347281","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70fda221-o-ring-dash-221-silicone","provider":"Voomi Supply","version":"1.0","type":"link"}
