It features a 9.484-inch inside diameter, a 9.75-inch outside diameter, and a 0.125-inch round cross section with a Shore hardness of 70. The black Buna-N compound delivers excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Licensed HVAC technicians, plumbers, and fluid-system mechanics install this part as a static or dynamic face seal in a wide range of industrial and trade applications. Each package contains 2 O-rings.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial fluid-handling systems where petroleum-based lubricants, hydraulic fluids, or fuel contact is expected. Its Dash 272 sizing makes it a standard replacement in pumps, compressors, valves, and pipe fittings that call for this cross-section profile. The rated temperature range of -40 degrees F to 250 degrees F covers most HVAC, plumbing, and light industrial service conditions. It is not FDA approved for food-contact use, though the supplier notes a metal-detectable FDA variant designation in additional information.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003eDash 272 standard sizing: 9.484 inches ID, 9.75 inches OD, 0.125 inches thick\u003c\/li\u003e\n  \u003cli\u003eShore hardness of 70 for firm compression set and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eRound cross section for consistent sealing in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eSold in a 2-piece package; minimum order quantity of 1 package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Dash 272 replacement O-ring compatible with petroleum-based fluid systems including hydraulic circuits, fuel systems, compressors, pumps, and valves that specify a Buna-N seal at this cross-section size.

Always depressurize and de-energize the system before replacing any O-ring seal. Inspect the groove and mating surfaces for scoring or debris before seating the new ring. Avoid stretching the O-ring beyond the groove diameter during installation, and do not store unused rings near motors, ozone-generating equipment, or in direct sunlight.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 272\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9.484 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 9.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 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 (Hard)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\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 Fluids\u003c\/strong\u003e: Petroleum Products\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: 2\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: ZMSCH70MD272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51708379791666,"sku":"ZMSCH70MD272","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d98d1a9895e67559b9118021220d4e26.jpg?v=1788445821","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70md272-o-ring-dash-272-buna-n","provider":"Voomi Supply","version":"1.0","type":"link"}
