It measures 7.75 inches inside diameter, 8 inches outside diameter, and 0.125 inches thick with a round cross section. The Buna-N compound delivers reliable resistance to petroleum-based fluids and excellent compression set recovery, making it a go-to elastomer choice for licensed plumbers, HVAC technicians, and mechanical contractors working with oil-carrying lines, pump assemblies, and valve bodies.\u003c\/p\u003e\n\u003cp\u003eThis O-ring suits residential and commercial applications where petroleum product exposure is a constant factor. Typical installations include pump flanges, hydraulic fittings, compressor housings, and large-diameter valve seats. The 70-durometer hardness provides a firm, stable seal under moderate compression loading. Rated for operating temperatures from -40 degrees F to 250 degrees F, it handles the thermal cycling found in HVAC refrigerant-adjacent assemblies and fluid transfer systems. Sold in a package quantity of 5.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) elastomer — the most widely used O-ring material for petroleum product resistance\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating provides firm sealing with good tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 250 degrees F for demanding thermal environments\u003c\/li\u003e\n  \u003cli\u003eRound cross section, Dash 265 standard sizing for predictable groove fit\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eShould not be stored in direct sunlight or near motors and electrical equipment that may generate ozone\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products and petroleum-based fluids.

Always depressurize and de-energize the system before removing the old O-ring and inspect the groove for damage or debris prior to seating the new ring. Lubricate the O-ring with a compatible fluid or assembly lubricant before installation to prevent rolling or tearing. Do not stretch the O-ring over sharp edges or hardware threads without proper protection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 8 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\u003eDash Number\u003c\/strong\u003e: 265\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (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\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\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: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\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: ZMSCH70265\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717371003186,"sku":"ZMSCH70265","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74d1c031c97b2d83d89be746a897434b.jpg?v=1788539307","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70265-o-ring-dash-265-nbr","provider":"Voomi Supply","version":"1.0","type":"link"}
