Vietnamcan is right. I took the first few turns of the thread off with a bench grinder because the thread is not quite right and can't wind in enough to lock in. Also remove the rubber washer off the fitting that goes into the 9kg as it stops it getting in far enough. It still seals perfectly without leaks. Remember I'm not responsible if you do some numbnuts job and fry yourself.
I had an old regulator lying around that was faulty and id replaced, i cut the end off it to get the screw in piece, and you are able to screw apart the new adapter hose, and remove the fitting and replace it with the fitting i took off the old regulator.
There is some thread locker on the threads of the brass fittings on the adaptor hose, i needed to apply some gentle heat from gas torch to release it, then it came apart nicely.
