Rated at 70 Shore hardness, this O-ring is designed for sealing applications that demand a wide operating temperature range, from -80 degrees F to 450 degrees F. Silicone compound provides good dry heat resistance along with strong weather and ozone resistance. Plumbers, HVAC technicians, and general industrial maintenance professionals install these in fluid, pneumatic, and mechanical assemblies where reliable static or low-motion sealing is required. Each package contains 10 O-rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial maintenance, repair, and retrofit applications involving oils, chemicals, and solvents where limited oil exposure is acceptable. The Dash 228 size is a standard AS568 designation, making it straightforward to cross-reference against existing specifications. Typical applications include pump housings, valve bonnets, pipe fittings, and equipment access covers where elevated or sub-zero temperatures cycle repeatedly. This is not a high-oil-immersion compound; consult material compatibility data when prolonged petroleum exposure is expected.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWide temperature range: -80 degrees F to 450 degrees F continuous service\u003c\/li\u003e\n\u003cli\u003eRound cross section, 0.125 inches thick, Dash 228 standard AS568 sizing\u003c\/li\u003e\n\u003cli\u003e70 Shore hardness rated Hard for reliable compression set resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents in limited-exposure applications\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or ambient-exposed installations\u003c\/li\u003e\n\u003cli\u003eSold in packs of 10, minimum order quantity of 1 pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 228 replacement O-ring for any application requiring a 2.25 inches ID by 2.5 inches OD by 0.125 inches thick silicone seal.

Clean the groove and mating surfaces of debris and old sealant before seating the new O-ring. A light coating of compatible lubricant helps seat the O-ring without rolling or twisting during assembly. Silicone O-rings are generally not compatible with silicone-based lubricants; use a compatible grease per the equipment manufacturer guidance.\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\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 228\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.25 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: 0.125 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 (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 exposure)\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\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: ZMSCS70228\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723318362418,"sku":"ZMSCS70228","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2db411f1e3b5c6fce2ce1957c859a44b.jpg?v=1788603150","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70228-silicone-o-ring-dash-228-10pk","provider":"Voomi Supply","version":"1.0","type":"link"}
