The DeWalt 3/8 in. x 7/16 in. SAE Flare Nut Wrench is a purpose-built hand tool designed for precision on hard-to-reach flare fittings. With a two-end, open-end design, this wrench gives you the exact SAE sizes you need without swapping tools in the middle of a tight job—from brake lines to fuel lines and A/C refrigerant connections.
- End 1 = 3/8", End 2 = 7/16" for quick, on-the-fly switching between common flare nut sizes.
-
Open-ended jaws: Narrow profiles slip into crowded areas where boxed ends can’t reach, reducing the risk of rounding flare nuts.
-
Durable construction: Made from chrome vanadium steel for lasting strength and resilience under high-torque demands.
-
Protected finish: Polished chrome provides corrosion resistance and easy cleanup in automotive environments.
-
SAE flare fittings: Specifically optimized for SAE flare nuts on automotive, motorcycle, and HVAC lines—where a precise fit matters.
-
Retail-ready: Carded packaging supports easy inventory display and quick grab-and-go for professionals on the shop floor.
Who benefits most: automotive technicians, motorcycle enthusiasts, HVAC installers, and DIYers who routinely service brake lines, fuel lines, or A/C refrigerant connections. If you’ve ever struggled with a stubborn flare nut and flattened a nut or damaged adjacent fittings, this DeWalt wrench is designed to minimize that risk with two secure, correctly sized ends.
Why this wrench stands out from generic alternatives:
- Fixed two-size design eliminates the need to carry multiple individual wrenches for common SAE flare nuts.
- Chrome vanadium steel construction delivers reliable torque without deformation, even when working in cramped spaces.
- Open-end jaws are machined for a precise bite, helping you avoid slippage and nut rounding in high-torque scenarios.
Practical tips for best results: position the correct end securely around the flare nut, apply steady, straight-on pressure, and avoid side-loading the jaw to prolong tool life. This wrench is ideal for standard SAE flare nuts encountered in most automotive and HVAC maintenance tasks, offering a compact, durable solution when every inch of space counts.
