Getting the Right-Size Torque Wrench Head

raul4817 | Posted in General Questions on

I’m installing my minisplit next week. Problem in my robinair torque wrench kit only goes up to 29mm.

This unit takes a 3/4″ line. I’ve matched the flare nut to a 32mm socket in the garage. I’m using a jmf ez pull lineset with manufacturer provided nuts.
Problem is I can’t find this head open ended online. The yellow jacket adjustable only goes up to 30mm from what I’ve read.

How do guys torque this down to the appropriate specs??

Where can I purchase one that will fit properly.

I’ve checked test equipment depot and grainger.
