How Do You Remove These Hoses?

As I'm in the process of taking my AC system apart, I was wondering if anyone knew off-hand the size of the large nut on the AC hose in the attached photo? The largest open-end wrench I have is 7/8, and that's to small.

In addition, I was wondering what the best way was to loosen that nut and the one in the other photo without over-stressing anything, as I can't seem to get a counter-hold on anything in the second photo?

DO they usually have to be torched to loosen them?

Thanks in advance.

Bill

That is probably 24 mm.
You need 2 wrenches to hold opposite parts. I fit the wrenches so there is small angle between them and then squeeze them together with palm of my hand.
Beware those are soft connectors so make sure you have well fitting wrench to not round up the corners.

Thank you. Someone in another forum said it was 27mm. So, I'm still not sure which one to get? Or could it be that one of you is talking about one of the nuts, and the other is talking about the other nut

In the 2nd photo, is it the big nut or the little nut that turns?

You should buy a set and flare wrenches are advisable.
If you have Harbor Freight Tools near by they sell them pretty cheap and decent quality.
Don't you have metric tape measure or scale?
