Our old cooker is a New World 55HLG and after many years of great service it's time to get rid.
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?
