I'll not bore you with details but for various reasons we've picked up a
secondhand but pristine New World 55THLG to replace it, so exact same make
and model coming out and going in.

Unfortunately the new one doesn't have a flexible hose fitted so being as
the old one is perfectly fine I'm thinking it should be alright to swap it
to the new cooker.

The wall end is a bayonet fitting so no problem there but, is it just a
case of screwing the hose 'as is' into the cooker end or is there some
special gobbo/gunge/tape that has to be applied to the threads first?

The thicker PTFE tape for gas comes in a yellow rather than white reel. Don't
tell anyone I said so.

Said what?? lol
