It measures 2.563 inches inside diameter, 2.75 inches outside diameter, and 0.094 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard category. The fluoroelastomer compound delivers strong resistance to petroleum-based fluids, high temperatures up to 400 degrees F, and low gas permeability, making it a reliable choice for HVAC, plumbing, refrigeration, and industrial sealing applications. Licensed tradespeople and maintenance technicians install these during equipment servicing and seal replacement work.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial systems where exposure to petroleum products, fuels, hydraulic fluids, and elevated temperatures is expected. The Dash 145 designation follows standard AS568 sizing, allowing straightforward cross-referencing on valves, pumps, fittings, compressors, and manifolds that call for a Dash 145 profile. The low compression set rating helps maintain a reliable seal over extended service intervals. Each order ships as a pack of 10 pieces, supporting fleet servicing and preventive maintenance stock. The fluoroelastomer material also handles vacuum service conditions with low permeability, which extends its use to refrigeration valve assemblies and vacuum pump connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F service temperature\u003c\/li\u003e\n  \u003cli\u003eDash 145 AS568 standard sizing: 2.563 inches ID, 2.75 inches OD, 0.094 inches thick\u003c\/li\u003e\n  \u003cli\u003eShore 70 hardness with low compression set for long-term sealing integrity\u003c\/li\u003e\n  \u003cli\u003eGood resistance to petroleum products, fuels, and a wide range of chemicals\u003c\/li\u003e\n  \u003cli\u003eSuitable for vacuum service and low gas permeability applications\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 10 for maintenance stock and multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service seal for any equipment requiring an AS568 Dash 145 O-ring in a fluoroelastomer or Viton-compatible material, including valves, pumps, compressors, and fittings that contact petroleum products or operate at elevated temperatures.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics during scheduled maintenance or component overhaul. Always depressurize and isolate the system before replacing seals, and verify the groove dimensions match the Dash 145 profile before installation. Lightly lubricating the O-ring with a compatible lubricant eases installation and reduces the risk of twisting or cutting the seal. Follow applicable codes and equipment manufacturer guidelines for torque and reassembly procedures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fluoroelastomer (Viton)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 145\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 2.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.094 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShore Hardness\u003c\/strong\u003e: 70 (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -15 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 400 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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 pieces\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: ZMSCV70145\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691178000690,"sku":"ZMSCV70145","price":16.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/08a5734faa64077af9c502cfe433e21e.jpg?v=1788281111","url":"https:\/\/voomisupply.com\/products\/value-collection-zmscv70145-viton-o-ring-dash-145-10-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
