With a 1.75-inch inside diameter, 1.875-inch outside diameter, and a 0.0625-inch round cross section, this Dash 031 O-ring provides a consistent seal in assemblies where dimensional precision matters. The silicone compound gives it a wide usable temperature range of -80 degrees F to 450 degrees F, making it suitable for both low-temperature exposure and sustained dry heat conditions. Hardness is rated at 70 Shore A. Installers and technicians working in environments with temperature swings, ozone exposure, or weathering demand will find this compound appropriate for the task.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in residential and light commercial HVAC equipment, plumbing fittings, pump housings, valve bodies, and chemical handling assemblies where a reliable face or groove seal is required. The silicone material offers good compatibility with oils, certain chemicals, and solvents, though oil resistance is limited and should be evaluated against the specific application. Each order package contains 25 O-rings, allowing technicians to stock a useful quantity for service calls or production line use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 031 designation: 1.75 inches ID x 1.875 inches OD x 0.0625 inches thick\u003c\/li\u003e\n\u003cli\u003eSilicone compound rated from -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness with round cross-section profile\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 in appropriate concentrations\u003c\/li\u003e\n\u003cli\u003eSold in a 25-piece package with a minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service O-ring for any assembly calling for a Dash 031 silicone O-ring with a 1.75-inch inside diameter and 1.875-inch outside diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of O-rings should be performed by a qualified technician familiar with the sealing assembly. De-energize, depressurize, and drain the system before replacing any O-ring. Inspect the groove and mating surfaces for nicks or burrs that could damage the new seal. Avoid using petroleum-based lubricants with silicone O-rings unless confirmed compatible with the compound and the media being sealed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 031\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\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 With\u003c\/strong\u003e: Oils, Chemicals, Solvents\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: 25\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: ZMSCS70031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722336403762,"sku":"ZMSCS70031","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aff85a2e1132d9a632f43be8913a016b.jpg?v=1788589605","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscs70031-silicone-o-ring-dash-031","provider":"Voomi Supply","version":"1.0","type":"link"}
