It measures 2.125 inches inside diameter, 2.5 inches outside diameter, and 0.1875 inches (3\/16 inches) thick, conforming to Dash 330 sizing. With a hardness rating of 70 Shore A, this O-ring is suited for static and dynamic sealing applications that demand reliable performance across a wide temperature range. Silicone construction provides good dry heat resistance and strong weather and ozone resistance. Licensed HVAC technicians, plumbers, and maintenance professionals commonly specify this material when sealing joints exposed to heat cycling or outdoor environments.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is appropriate for residential and light commercial applications involving oils, chemicals, and solvents where silicone compatibility has been confirmed. It is recommended for systems requiring service across an extended temperature range, from -80 degrees F to 450 degrees F. Typical install scenarios include shaft seals, pipe connections, valve bodies, and equipment housings. Note that this silicone formulation offers limited oil resistance, so verify fluid compatibility before specifying it in high-oil-concentration environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 330 standard sizing: 2.125 inches ID, 2.5 inches OD, 0.1875 inches thick\u003c\/li\u003e\n  \u003cli\u003eSilicone material rated for -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness for firm, consistent sealing compression\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n  \u003cli\u003eCompatible with oils, chemicals, and solvents (limited oil resistance — verify application)\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-piece pack with a minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 330 replacement O-ring for any gland or groove machined to accommodate a 2.125-inch ID silicone O-ring per AS568 sizing conventions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with the sealing system being serviced. Power down or depressurize the system completely before replacing any O-ring. Inspect the gland groove for nicks, corrosion, or debris before seating the new ring. Avoid twisting the O-ring during installation, as torsional stress reduces service life.\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\u003eDash Number\u003c\/strong\u003e: 330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (3\/16 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\u003eCompatible Media\u003c\/strong\u003e: Oils, Chemicals, Solvents (limited oil resistance)\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\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: ZMSCS70330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698010325298,"sku":"ZMSCS70330","price":15.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/792989f58b47d995e8f20d92a317784f_8cb91c9c-0c25-41ed-b532-d1eb796e5c21.jpg?v=1788356729","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70330-silicone-o-ring-dash-330-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
