It measures 6 inches inside diameter, 6.188 inches outside diameter, and 0.0937 inches thick with a round cross section. Hardness is rated at 70 Shore A. This O-ring delivers excellent resistance to petroleum-based fluids, strong compression set performance, and good tear and abrasion resistance. It is suited for use in plumbing, hydraulic, and HVAC systems where petroleum product exposure is a routine service condition. Licensed tradespeople and experienced technicians install this part as a replacement seal in pumps, valves, fittings, and mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for residential and light commercial applications where a standard Buna-N seal in the Dash 163 size is specified. Typical install scenarios include pump shaft seals, valve body seals, and pipe flange connections in plumbing and HVAC systems. The part is rated for service from -40 degrees F to 250 degrees F, making it suitable for a wide range of operating environments. It meets SAE and MIL-Spec standards. Compatible materials include petroleum products and petroleum-based hydraulic fluids. Each package contains 25 O-rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum fluid resistance\u003c\/li\u003e\n\u003cli\u003eDash 163 standard sizing: 6 inches ID, 6.188 inches OD, 0.0937 inches thick\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent sealing in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating for firm, reliable compression set\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eSold in a package of 25 units\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 163 Buna-N O-ring replacement for use in pumps, valves, fittings, and mechanical assemblies that specify a 6 inch ID nitrile seal compatible with petroleum-based fluids.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eO-ring installation should be performed by a qualified plumber, HVAC technician, or mechanic following the equipment manufacturer's service procedures. Always depressurize and de-energize the system before removing any sealing components. Inspect the O-ring groove for nicks, corrosion, or debris before installing the new seal. Do not store unused O-rings in direct sunlight or near motors or other electrical equipment that may generate ozone, as this degrades Buna-N elastomer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 163\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 6.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 6.1880 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0937 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 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: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: ZMSCH70163\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701915255090,"sku":"ZMSCH70163","price":16.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a956308e11fcd6520f7b9665c4e1c1b.jpg?v=1788406821","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70163-o-ring-6-inch-id-nbr-dash-163","provider":"Voomi Supply","version":"1.0","type":"link"}
