Each wrench features a 0-degree offset flare nut end on both sides, giving the user full contact around the nut hex for reduced slippage. The set covers 3\/8 inch by 7\/16 inch, 1\/2 inch by 9\/16 inch, and 5\/8 inch by 11\/16 inch, spanning the most common SAE tubing nut sizes found in residential and light commercial HVAC and plumbing work. The set weighs 0.72 pounds total.\u003c\/p\u003e\n\u003cp\u003eThis wrench set is a standard tool for HVAC technicians tightening or loosening flare fittings on copper refrigerant lines, as well as plumbers working brake and fuel line connections. The 0-degree offset profile keeps the wrenches flat against the work surface, making them practical in tight equipment cabinets and confined mechanical spaces where angled wrenches cannot seat properly. Professional installers and service techs commonly reach for this set when servicing split systems, mini-splits, and any application using SAE flare fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-piece set covers 3\/8 x 7\/16 inch, 1\/2 x 9\/16 inch, and 5\/8 x 11\/16 inch SAE sizes\u003c\/li\u003e\n  \u003cli\u003eFlare nut end design wraps around the nut hex to reduce rounding on soft brass and aluminum fittings\u003c\/li\u003e\n  \u003cli\u003e0-degree offset keeps wrench profile flat for use in confined spaces and equipment panels\u003c\/li\u003e\n  \u003cli\u003eSAE sizing matches standard domestic refrigerant and fuel line flare fittings\u003c\/li\u003e\n  \u003cli\u003eLightweight set at 0.72 pounds for easy transport in a field tool kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SAE flare nut fittings across residential and light commercial HVAC, plumbing, and refrigeration applications requiring 3\/8 inch through 11\/16 inch wrench sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFlare nut wrenches are a hand-tool application requiring no power source, but technicians should ensure system refrigerant or fluid lines are properly recovered or isolated before loosening any fitting. Always confirm the correct wrench size seats fully around the nut before applying torque to avoid deforming the fitting. Work performed on refrigerant lines must comply with applicable EPA Section 608 regulations and local mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSet Contents\u003c\/strong\u003e: 3\/8 x 7\/16 inch, 1\/2 x 9\/16 inch, 5\/8 x 11\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\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 Standard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.72 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each (set of 3)\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: CFNWS0-05\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRESCENT","offers":[{"title":"Default Title","offer_id":51343019540786,"sku":"CFNWS0-05","price":22.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310472338.jpg?v=1782013999","url":"https:\/\/voomisupply.com\/products\/crescent-cfnws0-05-flare-nut-wrench-set-sae-0-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
