Measuring 0.875 inches inside diameter, 1.125 inches outside diameter, and 0.125 inches thick, this round cross-section ring is molded from silicone with a Shore A hardness of 70. Its rated temperature range spans -80 degrees F to 450 degrees F, making it well suited for applications that demand dry heat resistance and reliable sealing under thermal cycling. Each package contains 100 rings.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in HVAC, plumbing, refrigeration, and general industrial assemblies where the seal must withstand elevated temperatures, ozone exposure, and weathering. It is a common fit for shaft seals, valve seats, pump housings, and fluid line connections in residential and light commercial equipment. Technicians and maintenance professionals install these rings wherever a Dash 212 size silicone seal is specified. Note that silicone offers limited resistance to petroleum-based oils, so verify fluid compatibility before use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTemperature range of -80 degrees F to 450 degrees F suits wide thermal cycling demands\u003c\/li\u003e\n\u003cli\u003eRound cross-section silicone construction provides consistent sealing compression\u003c\/li\u003e\n\u003cli\u003eShore A hardness rating of 70 balances flexibility with resistance to extrusion\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance extends service life in exposed installations\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents in appropriate concentrations — verify specific fluid compatibility\u003c\/li\u003e\n\u003cli\u003eSold in a package of 100 rings for shop stock or bulk service use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 212 O-ring replacement for any application calling out a 0.875-inch ID silicone seal with a 0.125-inch cross section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of O-rings should be performed with the mating assembly depressurized and fully de-energized or isolated from fluid flow. Lubricate the ring with a compatible fluid or silicone grease before seating to prevent tearing during assembly. Avoid rolling or twisting the ring into the groove, as this causes uneven compression and premature failure. Confirm groove dimensions match the Dash 212 cross section before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 212\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 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 With\u003c\/strong\u003e: Oils, Chemicals, Solvents (verify specific compatibility)\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: 100\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: ZMSCS70212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51706619724082,"sku":"ZMSCS70212","price":16.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e2f8baa4173b84f7b5871d1d45ab3b1.jpg?v=1788435728","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70212-silicone-o-ring-dash-212-pk100","provider":"Voomi Supply","version":"1.0","type":"link"}
