How do these come off?
Discussion
No, but you may have helped all the same. I am thinking that perhaps the bodyshell has those s/t type studs attached to it similar to those that retain the underside covers via a plastic nut and the middle "screw" is nothing but a fancy nut. And the one I tried is somewhat tight to release. Well that's my hope anyway. If the stud is fine threaded and there is a metal insert in the "screw" (nut), then removing will possibly need to be destructive.
The allen key should ( in theory ) unscrew , theres a threaded stud from the bodywork that it screws into.
I normally use a trim tool to lever them off , as long as you lever it straight and dont bend it then the stud wont break.
Try turning it as you lever it.

Many thanks for this Demort. Is it a self tapping (fast thread) type or a fine bolt type thread, what am I to expect? Is the "screw" 100% plastic or (if the stud thread is fine) is there a metal insert?I normally use a trim tool to lever them off , as long as you lever it straight and dont bend it then the stud wont break.

Thanks a zillion.
My problem is a leak at one refrigerant union, oddly the union that seemed to be in bad shape and I struggled to separate, is fine, the larger one which looked very pretty, is still leaking despite an o-ring change.
The Allen key is made of plastic only , there is no insert in it.
The thread on all porsches is a course thread.
Im assumeing you have a leak at the two rear a/c pipes on a 996 , if you have got them undone without stripping the thread then you have already done the hard part !
I have unfortunatly broken many of them in the past trying to get them undone and its not a cheap job to replace thoose pipes.
Btw its not the end of the world if the stud does break , bodyshops can weld a replacement with a type of weld gun.
Opps i didnt read you still have a leak , the seal should be a proper a/c seal and the surfaces have got to be totally clean , if it leaks after that then i suspect the pipe is pourous , i would consider changing the pipe from front to rear as a diy job , its not too hard , the pipe that goes over the engine is a little more complcated but could be done at home , ill happily talk you through it if it comes to pipe changing.

Hi Demort thanks once again, well beyond the call of duty.
I will grasp the screw with a pair of mole grips to assist in removal.
Yes removing one Allen bolt to separate one coupling required interesting measures, but it came off in the end.
Oddly that one has sealed well, the other one where everything looked fine is leaking. The main pain is paying for a regas every time but my (now very well acquainted) a/c tech may be a bit understanding, I called him up the day after, as soon as the leak was evident, and he intimated as much.
With any luck the pipe is fine, doing many things on these cars is a pain what with everything tightly packaged, and so many steel/ally connectors practically welded together.
