It measures 0.455 inches inside diameter, 0.561 inches outside diameter, and 0.0468 inches thick. The Dash 8-013 designation identifies it within standard O-ring sizing charts. This ring is used as a backup seal to prevent extrusion in static and dynamic sealing assemblies across plumbing, hydraulic, pneumatic, and HVAC systems. It is installed by licensed plumbers, HVAC technicians, and mechanical contractors working with fluid or gas-carrying components.\u003c\/p\u003e\u003cp\u003eThis O-ring suits applications requiring a hard, extrusion-resistant backup seal in moderate-to-high pressure environments. Its NBR construction provides solid resistance to petroleum-based oils, fuels, and water, making it appropriate for use in valves, fittings, cylinders, and hydraulic connectors found in residential and light commercial mechanical systems. The operating temperature range of -40 to 250 degrees F covers most standard HVAC, plumbing, and fluid power service conditions. This product is sold in a package quantity of 100 rings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRectangular cross-section profile functions as a backup ring to resist seal extrusion under pressure\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating provides high resistance to deformation and blowout\u003c\/li\u003e\n\u003cli\u003eNBR material compatible with petroleum oils, fuels, and water-based fluids\u003c\/li\u003e\n\u003cli\u003eOperating range of -40 to 250 degrees F suits most mechanical system environments\u003c\/li\u003e\n\u003cli\u003eStandard Dash 8-013 sizing for straightforward cross-reference and replacement\u003c\/li\u003e\n\u003cli\u003ePackage quantity of 100 units supports service stock and bulk repair work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 8-013 backup O-ring replacement for use in any groove or assembly calling for a 0.455 inches ID by 0.561 inches OD rectangular NBR seal rated at 90 durometer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified tradesperson familiar with static or dynamic sealing assemblies. De-pressurize and isolate the system before disassembly. Inspect the mating groove for damage, scoring, or contamination before seating the new ring. Do not roll, twist, or overstretch the ring during installation, as distortion reduces sealing effectiveness.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.455 inches (11.55 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.561 inches (14.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0468 inches (1.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 Durometer (Extra Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (NBR)\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\u003eDash Number\u003c\/strong\u003e: 8-013\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\u003eWeight\u003c\/strong\u003e: 0.04 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: ZMSCHB90013\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720072888626,"sku":"ZMSCHB90013","price":20.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bbbcceebcc98f31c0d76bce29370f44a_9b04812c-60fc-4ac8-8238-1448eeff0f82.jpg?v=1788560670","url":"https:\/\/voomisupply.com\/products\/value-collection-zmschb90013-o-ring-nbr-90-duro-dash-8-013","provider":"Voomi Supply","version":"1.0","type":"link"}
