What the latest preferred method of getting a seal on parallel threads like a bib tap to the wall plate (for an outside tap) ? PTFE tape is often suggested but some folks say you need some compression for this to work, so it should only be used on tapered threads like radiator tails. Or should I go for old fashioned hemp and boss white ?
Thanks, Simon.

Ideally, when you screw it in fully the flange on the tap meets the face of the wall plate. Add a fibre washer and you can hopefully get the tap orientation OK. If it's miles out, try two fibre washers. Or you can make up a "string" of PTFE tape and clamp that between the flanges. Or you may get away with a suitably sized O-ring. I'd always have a generous layer of PTFE tape on the threads anyway. Boss white and hemp only as a last resort.

PTFE tape plenty good enough for the job. 10-12 turns wound with the thread will give a good seal. As it's on an ouside tap then will likely to connected to the mains and hemp and boss white strictly forbidden.
Don't be tempted to use washers as you will find it very difficut to get the tap lined up nicely.
