17 × 19 mm Flare-nut Wrench from Yato packs reliable workshop-grade durability thanks to its chrome-vanadium (CrV 6140) steel construction — ready to take on brake-line, hydraulic, or plumbing fittings without bending or breaking. A semi-open hexagonal design hugs nuts on multiple sides, reducing the risk of rounding or damaging soft fittings while giving a firmer, safer grip. Slight 15° head offset improves access in tight or awkward spaces, making it easier to get on stubborn nuts without contorting or stripping. Its polished, chrome-plated finish resists corrosion and helps keep friction low — ideal for use on brake lines, fuel lines, or other sensitive metal pipes. Whether you’re working on automotive braking systems, HVAC lines, or plumbing/hydraulic fittings, this wrench delivers dependable precision and makes tough jobs smoother.
