Measuring 0.239 inches inner diameter, 0.367 inches outer diameter, and 0.064 inches thick, this round cross-section seal is made from white silicone with a hardness rating of 70 Shore A. Silicone compound delivers a wide service temperature range of -80 degrees F to 450 degrees F, making it well suited for applications where standard nitrile or EPDM seals fall short. Sold in a package quantity of 50, this O-ring is installed by HVAC technicians, plumbers, and industrial mechanics working with threaded hydraulic and pneumatic fitting assemblies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is intended for O-ring boss (ORB) straight-thread port and tube fitting connections where a reliable face or port seal is required. Its silicone material provides good dry heat resistance and strong weather and ozone resistance, making it appropriate for outdoor-exposed systems and high-temperature lines. It carries limited oil resistance, so it is not the preferred choice for petroleum-fluid service lines. Typical applications include compressed air systems, water lines, HVAC refrigerant-adjacent fittings, and other systems demanding broad thermal tolerance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDash 902 O-ring boss gasket for straight-thread tube fittings\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -80 degrees F to 450 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross-section silicone construction with 70 Shore A hardness\u003c\/li\u003e\n  \u003cli\u003eGood weather and ozone resistance for outdoor and exposed installations\u003c\/li\u003e\n  \u003cli\u003eWhite silicone material — readily distinguishable from nitrile and EPDM seals during service\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 50 suits service van stocking and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an O-ring boss gasket for straight-thread tube fittings using the Dash 902 size standard.

Ensure the seating surface is clean and free of debris or damaged threads before installing the new O-ring. Lubricate the O-ring with a compatible fluid or assembly grease prior to installation to prevent tearing during make-up. Note that this silicone compound has limited oil resistance — verify fluid compatibility before installation in petroleum or hydraulic oil service.\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: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 902\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Diameter\u003c\/strong\u003e: 0.239 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.064 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\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50\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: ZMSCS70902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689189605682,"sku":"ZMSCS70902","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_7a1a4ecd-884f-445d-8023-8262223c6e3b.jpg?v=1788255891","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70902-silicone-o-ring-dash-902-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
