Manufactured from alloy steel with a full polish chrome finish, this wrench measures 7.614 inches in length and weighs 0.39 pounds. The standard pattern body provides solid engagement on hex nut flats, reducing the risk of rounding. Plumbers, HVAC technicians, and automotive service professionals reach for flare nut wrenches when working around fuel lines, brake lines, refrigerant line fittings, and compression fittings where an open-end wrench alone may slip.\u003c\/p\u003e\n\u003cp\u003eThis wrench covers two sizes in a single tool — 5\/8 inch on one end and 11\/16 inch on the other — making it well suited for residential and light commercial service work on tubing assemblies. Common applications include tightening flare fittings on refrigerant lines, servicing compression-style water supply connections, and working on vehicle fuel and brake line connections. The compact, single-wrench format reduces the number of tools needed when working in tight access panels or under dashboards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-size design: 5\/8 inch and 11\/16 inch on a single wrench\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for durability under high torque loads\u003c\/li\u003e\n  \u003cli\u003eFull polish chrome finish resists corrosion and simplifies cleaning\u003c\/li\u003e\n  \u003cli\u003eStandard pattern body fits hex nuts with tubing present\u003c\/li\u003e\n  \u003cli\u003e7.614-inch length provides clearance in tight work areas\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.39 pounds for reduced hand fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard hex flare nuts where tubing restricts access, including vehicle fuel and brake line fittings, refrigerant line connections, and compression plumbing fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlare nut wrenches are installed and removed by licensed HVAC technicians, plumbers, and mechanical service professionals. Always depressurize refrigerant lines or shut off water and fuel supply before breaking flare or compression fittings. Select the correct wrench size to avoid rounding the nut flats. Do not substitute an open-end wrench where a flare nut wrench is required, as tube interference can cause slippage and fitting damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Sizes\u003c\/strong\u003e: 5\/8 inch x 11\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 7.614 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Full Polish Chrome\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 099575816833\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: APEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 81683\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"APEX","offers":[{"title":"Default Title","offer_id":51344066740530,"sku":"81683","price":33.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310498381.jpg?v=1782028152","url":"https:\/\/voomisupply.com\/products\/apex-81683-flare-nut-wrench-5-8-x-11-16-inch-chrome","provider":"Voomi Supply","version":"1.0","type":"link"}
