It is built to grip hex fittings from two sides, reducing the risk of rounding soft brass or steel flare nuts common in HVAC refrigerant lines, fuel lines, and hydraulic connections. The wrench size is 11\/16 inch with a 6-point contact pattern, a head diameter of 1-17\/32 inches, and a head thickness of 1\/4 inch. The chrome-plated finish resists corrosion and simplifies cleaning after use. Licensed HVAC technicians, plumbers, and mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis crowfoot wrench is well suited for residential and light commercial service work where standard box-end wrenches cannot access inline fittings due to obstructions such as valves, manifolds, or adjacent tubing. Its open-side design allows the tool to slide onto a fitting from the side, making it practical for refrigerant service valves, fuel line connections, and brake line fittings. The 6-point geometry distributes torque evenly across the flats, which is critical when working with soft-material fittings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/16-inch wrench size fits common HVAC and plumbing flare nut sizes\u003c\/li\u003e\n  \u003cli\u003e6-point contact pattern reduces corner wear on soft fittings\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch head thickness allows access in confined spaces\u003c\/li\u003e\n  \u003cli\u003eChrome-plated finish provides corrosion resistance and easy cleanup\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B107.21 and Federal Specification GGG-C-1507b standards\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3\/8-inch drive ratchets and torque wrenches\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 3\/8-inch square drive ratchets and torque wrenches.

Always relieve system pressure and, where applicable, recover refrigerant or shut off fluid supply before loosening any fittings. Seat the crowfoot squarely on the fitting flats before applying torque to avoid slippage. When used on a torque wrench at an offset angle, apply the appropriate correction factor per the torque wrench manufacturer guidelines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 11\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 1-17\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Thickness\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Chrome-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B107.21, GGG-C-1507b\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Limited Lifetime Warranty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.8 inches L x 1.3 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: J4922HFL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51541236318514,"sku":"J4922HFL","price":57.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bfe6def07b36bb6942e200a2423df9c.jpg?v=1785870543","url":"https:\/\/voomisupply.com\/products\/proto-j4922hfl-flare-nut-crowfoot-wrench-11-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
