It worked fine for that application. ### ⭐ Ruined my whole project *by L***H on June 28, 2025* Value for money: This piece of junk didn’t work and now I have to call an HVAC contractor to recharge my 3 zone system. It never “clicked”. I over tightened my flare but and crushed the flare!!! I’ve used torque wrenches before.
