VANPO 1/2" Torque Wrench, 10-170 Ft-Lb, 38mm Jaw & Ratchet Head | Precision Tool for HVAC & Auto

• TWO WAYS TO USE – JAW & RATCHET HEAD: This adjustable torque wrench comes with a 38mm open-end jaw and a 1/2" 72-tooth ratchet head, both sharing a 14x18mm interchangeable interface. Use the jaw head to grip flare nuts on mini-split AC lines, heat pump piping, and plumbing fittings. Switch to the ratchet head for automotive lug nuts, motorcycle axle bolts, and engine fasteners. One interchangeable torque wrench does the work of an entire drawer of tools.
• INTERCHANGEABLE HEAD SYSTEM: The 14x18mm open end on this hvac torque wrench lets you swap heads in seconds — ratchet heads, open-end spanners, or torx heads. This modular design means one wrench body adapts to countless jobs: HVAC service ports, car brake calipers, motorcycle engine covers, and industrial hydraulic line fittings. A single interchangeable torque wrench that grows with your needs.
• HIGH ACCURACY & DUAL SCALE: Calibrated to ±3% accuracy in both clockwise and counterclockwise directions, this adjustable torque wrench ensures precise tightening from 10 to 170 ft-lb. The laser-engraved dual-range scale is clear, wear-resistant, and easy to read even in dim compressor cabinets or under a car chassis. Whether torquing a heat pump coupling or a truck lug nut, you hit factory specs every time.
• EASY-TO-FEEL 'CLICK' & AUTO-LOCK: Pull down the lock knob, set your desired torque, and release — it automatically rebounds to lock the value in place. When the preset torque is reached, this hvac torque wrench emits a clear, audible “click” and a tactile pulse through the handle. Foolproof feedback protects delicate aluminum AC fittings, carbon bike components, and cast engine parts from over-tightening.
• WIDE APPLICATION & HVAC TOUGH: This adjustable torque wrench excels in tight spaces. Use it on HVAC and refrigeration: mini-split and multi-split AC flare nuts, heat pump service valves, and compressor bolts. Automotive: lug nuts, spark plugs, brake caliper brackets, valve covers. Motorcycle: sprocket nuts, engine covers. Plumbing: water heater connections, compression fittings. All backed by a rugged build that handles daily shop and field use.

• Select and Attach Head — Choose either the 38mm open-end jaw for flare nuts or the 1/2" drive ratchet head for other fasteners. Ensure the head is securely attached to the 14x18mm interface on the wrench body.
• Set Desired Torque — Pull down the lock knob on the handle and rotate it to set the desired torque value on the dual-scale laser-engraved display (Ft-Lb or Nm). Release the knob to lock the setting.
• Apply Torque — Apply steady, continuous force to the handle until you hear and feel the distinct 'click' and tactile pulse, indicating the target torque has been reached. Avoid further tightening.
• Reset and Store — After use, reset the torque setting to its lowest value to relieve tension on the internal spring. Store the wrench and its heads in the included rugged blow-molded case to protect them from damage and corrosion.
