Each wrench features a flare nut (line wrench) end on both sides with a 0-degree offset, giving a flat working profile suited to tight inline connections. The set covers six metric sizes: 9MM x 10MM, 11MM x 12MM, and 13MM x 14MM. The set weighs 0.72 pounds total, making it a compact addition to a service bag. HVAC technicians, refrigeration mechanics, and plumbers routinely reach for this type of set when breaking loose or torquing metric flare fittings.\u003c\/p\u003e\n\u003cp\u003eThis wrench set is intended for metric flare nut applications common in residential and light commercial HVAC systems, hydronic heating lines, and automotive-style fuel and brake lines. The six-point line wrench opening grips the flare nut on multiple faces, reducing the chance of rounding the fitting during service. The 0-degree offset on both ends keeps the wrench flat to the work surface, which is useful in confined equipment spaces where angled tools cannot seat properly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-wrench set covering six metric sizes: 9MM x 10MM, 11MM x 12MM, and 13MM x 14MM\u003c\/li\u003e\n  \u003cli\u003eFlare nut (line wrench) ends on both sides of each wrench for full-contact grip on soft fittings\u003c\/li\u003e\n  \u003cli\u003e0-degree offset on both ends for flat, low-profile access in confined spaces\u003c\/li\u003e\n  \u003cli\u003eMetric sizing for use on metric flare and line fittings\u003c\/li\u003e\n  \u003cli\u003eLightweight set at 0.72 pounds for easy inclusion in a field service bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or supplemental tool for metric flare nut and line fitting applications in HVAC, refrigeration, plumbing, and related mechanical service work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlare nut wrenches are installed and removed by licensed HVAC technicians, refrigeration mechanics, and plumbers. Always recover refrigerant and depressurize or shut off fluid supply before loosening any line fitting. Use the correct size wrench to avoid rounding flare nuts — never substitute an adjustable wrench on soft metric fittings. Follow applicable trade codes, including IFGC or local mechanical codes, when working on fuel or refrigerant lines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Contents\u003c\/strong\u003e: 9MM x 10MM, 11MM x 12MM, 13MM x 14MM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type (Both Ends)\u003c\/strong\u003e: Flare Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOffset Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement System\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 037103336958\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: CRESCENT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CFNWS1-05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRESCENT","offers":[{"title":"Default Title","offer_id":51344622813490,"sku":"CFNWS1-05","price":21.73,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310472326.jpg?v=1782038202","url":"https:\/\/voomisupply.com\/products\/crescent-cfnws1-05-metric-flare-nut-wrench-set","provider":"Voomi Supply","version":"1.0","type":"link"}
