Q & A
"1x crescent wrench, 19 mm
•1x crescent wrench, 22 mm/24mm
•1x crescent wrench, 24 mm/27mm".
I understand the refrigerant hoses have specific torque settings for tightening them. I have a standard torque wrench to which I'd like to add "crow's foot" open end wrenches so that I can use it to torque the hose fittings properly.
What sizes are needed for assembly using a torque wrench? I don't want to purchase more than I need.
Thanks!
