It measures 3.25 inches inside diameter, 3.5 inches outside diameter, and 0.125 inches thick, conforming to Dash 236 dimensions. The durometer hardness is 70, placing it in the hard rating category. This O-ring is used to create static or dynamic seals in plumbing, HVAC, and industrial fluid systems. Installation is typically performed by licensed plumbers, HVAC technicians, and maintenance mechanics during assembly, repair, or preventive maintenance work.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for applications that require a wide temperature range and good dry heat resistance. The silicone compound performs from -80 degrees F to 450 degrees F, making it a common choice for high-temperature HVAC connections, chemical handling lines, and solvent-exposed assemblies. It offers good weather and ozone resistance. Note that oil resistance is limited, so it should not be specified as a primary seal in high-oil-concentration environments without verifying compatibility. Each pack contains 5 O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 236 standard sizing: 3.25 inches ID, 3.5 inches OD, 0.125 inches thick\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003e70 durometer hardness rating (hard) for firm, reliable sealing\u003c\/li\u003e\n\u003cli\u003eGood resistance to weather, ozone, dry heat, oils, chemicals, and solvents\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eSold in a pack of 5 to support service stock and multi-unit jobs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 236 replacement O-ring for use in plumbing, HVAC, and industrial applications requiring a silicone seal within the stated temperature and chemical resistance parameters.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut off fluid flow and relieve system pressure before replacing any O-ring. Inspect the groove and mating surfaces for damage, debris, or corrosion before seating the new ring. Lubricate the O-ring with a compatible silicone-based lubricant prior to installation to prevent tearing during assembly. Verify chemical and temperature compatibility with the specific media in the system before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 236\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\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\u003eHardness\u003c\/strong\u003e: 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: 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\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\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCS70236\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701798863154,"sku":"ZMSCS70236","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b80b8b68e0d0caa08261dbb123783f83.jpg?v=1788405150","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70236-silicone-o-ring-dash-236-5-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
