Review: Did the job! Got it fast! - I used this while installing a DIY mini split heat pump and I'm glad this wrench was available as the instructions really emphasize not under torquing or over torquing the connections. In retrospect I should have gotten the one that ranges from 5-45 ft lb as one of the fittings needed 40 and this one only goes up to 30 but at that point I had figured out what I needed to do to get the fittings tight but not too tight. The wrench was a confidence builder and I was able to get it next day. Thanks desertcart! As for accuracy I tried a regular torque wrench I have and this one set to 20 ft lb and they both seemed to click at about the same amount of force.

**Q: Does this torque wrench can torquing 3/8 and 1/2 flare nut?**
A: This will torque the smaller line (1/4 inch), but all the larger sizes require a larger torque wrench. For example, in my manual it states that for the next size up line (3/8 inch) requires 32-39 Nm. This one only goes to 30Nm.
