dunno marcus took mine to the local plumb centre,told em what i wanted to do and they fixed me up with fittings to suit(if memory serves me right it was in the region of about £20.00 in fittings)just take some brass hozelock connections with you and they should sort it all out to suit.it sounds a bind but it does save trawling through b&Q/homebase etc and probably works out cheaper imo.just about to post this when a new post came up about the level of gas in a bottle,check out hombases one from bp/fibreglass bottle that you can see the level of gas in it
