Use PTFE on the threaded part of the tail that you insert into the radiator.
As for the tails 'meeting the valves'. 3/4 inch ground IMO is best done with a smear of LSX.
1/2 inch (15mm) and you will have an olive on compression.
PTFE on this is a poor job.
There is no need for PTFE or jointing compound on the threads of compression or union fittings - the nuts just hold the joint together.
If the joint doesn't seal 'dry', just a smear of jointing compound on the olives of compression fittings or the joint faces of unions should be all that's needed.
If that doesn't work, there's usually something else amiss - grit in the joint, misaligned pipes, crushed olive etc. etc.
