It measures 1.5 inches inside diameter, 1.625 inches outside diameter, and 0.0625 inches thick. With a hardness rating of 70 Shore A, this O-ring provides a firm, reliable seal in static and light dynamic applications. It offers good resistance to dry heat, weather, and ozone, making it well suited for environments where temperature cycling or outdoor exposure is a concern. HVAC technicians, plumbers, and industrial service professionals install these rings as sealing elements in fittings, valves, and threaded connections.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for residential and light commercial HVAC systems, plumbing assemblies, pool and spa equipment, and general industrial fluid handling where silicone elastomer is compatible with the media. It is listed as compatible with oils, chemicals, and solvents, though oil resistance is noted as limited. Applications requiring consistent sealing across a broad temperature range are a primary use case. Each order ships as a package of 25 rings, allowing technicians to stock a supply for routine service calls.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTemperature range of -80 degrees F to 450 degrees F supports demanding thermal cycling environments\u003c\/li\u003e\n\u003cli\u003eRound cross section and Dash 029 sizing for straightforward groove-fit installation\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness provides a firm seal in static and low-dynamic sealing applications\u003c\/li\u003e\n\u003cli\u003eSilicone compound offers good weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents — note limited oil resistance\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 25 for efficient field and shop stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 029 O-ring replacement for fittings, valves, and fluid connections that specify a silicone elastomer seal in HVAC, plumbing, pool, and general industrial service.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with sealing component replacement in pressurized systems. Shut off and depressurize the system before removing any fitting or valve. Inspect the O-ring groove for damage, debris, or corrosion before seating the new ring. Avoid twisting the O-ring during installation; a light application of compatible lubricant helps seat the ring evenly and reduces the risk of installation damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 029\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\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\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Media\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\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZMSCS70029\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51699730350386,"sku":"ZMSCS70029","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf2023080b9f828187848f5e7fd8365b.jpg?v=1788379991","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70029-silicone-o-ring-dash-029-25-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
