It features a 6-point opening that grips flat sides of flare nuts and line fittings, reducing the risk of rounding. The head diameter measures 1-19\/32 inches with a head thickness of 1\/4 inch, keeping it compact enough to fit in tight spaces around refrigerant lines, fuel lines, and hydraulic fittings. The chrome-plated finish resists corrosion and makes the tool easier to wipe clean. It meets ASME B107.21 and Federal Specification GGG-C-1507b and is backed by a limited lifetime warranty.\u003c\/p\u003e\u003cp\u003eThis crowfoot wrench is suited for HVAC technicians, plumbers, and mechanics working on flare fittings in confined areas where a standard box-end wrench cannot be positioned. Common applications include tightening or loosening 3\/4-inch flare nuts on refrigerant line sets, fuel supply lines, and hydraulic or pneumatic tubing connections. The crowfoot design allows torque wrench use, making it appropriate for installations where specified torque values must be met.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch size with 6-point profile for secure grip on flare nuts and line fittings\u003c\/li\u003e\n\u003cli\u003eHead diameter of 1-19\/32 inches and head thickness of 1\/4 inch for access in tight spaces\u003c\/li\u003e\n\u003cli\u003eChrome-plated finish for corrosion resistance and easy cleaning\u003c\/li\u003e\n\u003cli\u003eMeets ASME B107.21 and Federal Spec GGG-C-1507b\u003c\/li\u003e\n\u003cli\u003eCompatible with standard drive ratchets and torque wrenches for controlled fastening\u003c\/li\u003e\n\u003cli\u003eBacked by a limited lifetime warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4-inch flare nuts and line fittings; fits standard drive ratchets and torque wrenches in inch-measurement tooling setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed onto a compatible drive ratchet or torque wrench before use. Always ensure the refrigerant system, fuel supply, or hydraulic circuit is properly isolated and depressurized before loosening or tightening flare fittings. Verify the correct wrench size against the fitting before applying torque to avoid rounding the nut. HVAC work involving refrigerant lines should be performed by EPA Section 608 certified technicians.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWrench Size\u003c\/strong\u003e: 3\/4 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: 1-19\/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: 1.94 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: 2 inches L x 1.5 inches W x 0.5 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: J4924HFL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PROTO","offers":[{"title":"Default Title","offer_id":51544585994546,"sku":"J4924HFL","price":54.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1eba90d19c2b0d0f76c1dc2d4d0398d2.jpg?v=1785930713","url":"https:\/\/voomisupply.com\/products\/proto-j4924hfl-flare-nut-crowfoot-wrench-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
