I am just learning about these also but from what I read in here it sounds like you unscrew the inner piece first then the outside sleeve. I believe the outside sleeve is left hand thread. It will take a wrench.
I also want to ask a question about these re-usable hose ends. Do they also make them in NPT not just JIC?

I commented in that thread,
To take them apart I would think like an other compression fitting you would unscrew the back nut closest to the hose to release the hose.
Usually you tighten the back nut down which compresses the hose onto a steel tube making the leak proof connection, so it would be reverse of that.
I've no real experience so find out for sure before you try, I'm sure you know not to try it when line are pressurized.

Eric is correct. The Parker web site has instructions for assembling the fittings.
Fittings are available in male NPT, and the pipe has a chamfer to attach to female pipe swivel fittings as well.
Note that the fitting must be compatible with the hose. Each fitting is designed for a very narrow range of hose ID's and OD's, and in some cases for the type of wire (braid, spiral, one wire, two wire, etc.). It is advisable to buy the hose and fittings from the same place (like my favorite Discount Hydraulic Hose) to be sure they are compatible. Otherwise, the hose may blow out of the fitting at high pressure.

Put the hex over the hose in a vise with fitting up put a box wrench over fitting to the hex next to the hose hex and turn it counter clockwise (lefty loosey) till it unwinds from the end of hex and hose.
It actually is threaded in the steel hex that hose is in and at the same time it screws in to the hose and compresses it against the id of the hex.
Then put the hose in the vise and turn hex clockwise this is a left hand thread to remove it.

page 58 of the above link is how to install it.

This is a good answer and Eric is correct.
It may have been me who gave the link in another thread?
What I do is hold the steel hose hosel in a vice and unscrew the inner fitting. I think it's a 5/8" wrench. Then, hold the hose in the vise using 2 pieces of rubber. I have rubber pieces that I used to hold golf shafts when regripping or assembling club heads. They work great. Anyway, the steel hose hosel is a left hand thread and takes a bigger wrench. Unscrew the hosel from the hose and you are done. You can reuse the fitting on another compatible hose like Farmerford said.
Here are a couple photos of the ones I did.
You can see them apart and together. Also how I held it in the vise.

Those fittings look a lot like the Air Force used on aircraft and GROUND POWER HYDRAULICS and some fuel lines back in the 1960-70 period. I do remember that those old fittings were 2 piece only. Picture #3 has a third part which looks like a locknut.
Gosh if I looked hard enough, I might even find a couple of them that I robbed off of a MARS RADIO power unit.

You're welcome JB...
I just got through doing that on my wife's tractor so I had the photos.
That locknut is not a third piece.
It is a solid machined nut which is part of the fitting that screws inside ... into the hose and hosel.

Aero-quip made these kinds of fittings with about any end that you could want from the o-ring flange on hp Cat machines to the npt for rock drills. Especially on the big sizes (1 1/2) they can be a bear to get together and apart. we used lots of lub and a strong vise in the hose room. They work and that could mean the difference between the equipment finishing the shift or being down for a day or so.
