It measures 5 inches inside diameter, 5.188 inches outside diameter, and 0.0937 inches thick. The silicone compound delivers a working temperature range of -80 degrees F to 450 degrees F, making it well-suited for high-heat and wide-swing thermal environments. The material also provides good resistance to weathering and ozone exposure. Licensed trades and maintenance technicians install this type of O-ring as a replacement seal in valves, flanges, pumps, and piping connections.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is used in residential and light commercial applications where silicone sealing compounds are specified. The Dash 159 designation conforms to standard AS568 sizing, simplifying cross-reference and replacement sourcing. Typical install scenarios include sealing threaded or flanged joints in HVAC equipment, hydronic systems, chemical-handling lines, and general plumbing assemblies where exposure to dry heat, ozone, or moderate chemical contact is expected. Each package contains 5 O-rings.\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\u003eRound cross section with Dash 159 AS568 standard sizing for straightforward cross-reference\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or ambient-exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents in limited-contact applications\u003c\/li\u003e\n  \u003cli\u003eHard durometer rating (70 Shore A) for dimensional stability under compression\u003c\/li\u003e\n  \u003cli\u003eSold in packs of 5 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 159 replacement O-ring for any application requiring an AS568-compliant seal with 5 inch inside diameter and silicone material construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eO-ring installation should be performed by a qualified technician following applicable codes such as NEC, IPC, or IFGC depending on the system being serviced. Isolate and de-pressurize the system and allow components to cool before replacing any seals. Inspect the O-ring groove for nicks, corrosion, or debris before seating the new ring. Avoid rolling or twisting the O-ring during installation to prevent premature seal failure.\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: 159\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.188 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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 contact)\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: 5\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: ZMSCS70159\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694149730610,"sku":"ZMSCS70159","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_dd5a3179-be87-4e00-9f3a-b5f4b675aaeb.jpg?v=1788320911","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70159-silicone-o-ring-dash-159-5in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
