It features a 12-point box end on a double-end head configuration, giving technicians a secure grip on soft flare nuts without rounding edges. The wrench spans 5\/8 x 5\/8 inches across both ends and measures 7-5\/8 inches overall length. Constructed from steel with a satin finish, it provides durability and corrosion resistance in shop and field environments. The 15-degree head offset angle allows clearance in tight spaces around tubing and fittings. Weighing 0.32 pounds, it is a lightweight addition to any trade tool kit.\u003c\/p\u003e\n\u003cp\u003eThis wrench is used in residential and light commercial HVAC, refrigeration, and plumbing applications where flare fittings must be tightened or loosened without slipping. The flare nut design keeps the wrench captured around tubing, preventing damage to soft brass or copper flare nuts. It suits technicians working on refrigerant line connections, gas line fittings, and other tubing assemblies that require controlled torque on flared connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end combination head spans 5\/8 x 5\/8 inches for consistent sizing across both ends\u003c\/li\u003e\n  \u003cli\u003e12-point box end provides multiple engagement positions in confined spaces\u003c\/li\u003e\n  \u003cli\u003e15-degree head offset angle improves clearance around tubing and adjacent fittings\u003c\/li\u003e\n  \u003cli\u003eSteel construction with satin finish for durability and reduced glare\u003c\/li\u003e\n  \u003cli\u003e7-5\/8 inches overall length delivers leverage without excessive bulk\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.32 pounds for extended use in field service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style hand tool for use with standard 5\/8-inch flare fittings found in HVAC, refrigeration, and plumbing tubing assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wrench is installed and used by HVAC technicians, refrigeration mechanics, and plumbers working on flare fitting connections. Always isolate refrigerant or shut off gas and fluid supply before loosening or tightening flare connections. Use the wrench as a backup tool in conjunction with a torque wrench where manufacturer torque specifications apply to flare joints. Avoid using extension bars or cheater pipes on flare nut wrenches, as over-torquing can crack flare seats.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 5\/8 x 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 7-5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Double End Combination Flare Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoints\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Offset Angle\u003c\/strong\u003e: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Satin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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: PROTO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: J3755T\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541460222258,"sku":"J3755T","price":52.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7113a39bf4d27fae4e7c5c2db32b6b74.jpg?v=1785876758","url":"https:\/\/voomisupply.com\/products\/proto-j3755t-combination-flare-nut-wrench-5-8-in-satin","provider":"Voomi Supply","version":"1.0","type":"link"}
