Hi big nev I’ve been trying to post on here but it says I have but I can’t see it ,don’t know if you can. Any way I’ll try again,I’ve added two pictures of the splice lok fittings I put on 3 yrs ago and they still hold the gas , if you google direct supply uk and search for splice lok it takes you straight there they are not cheap but it’s cheaper than all the pipes and a damn site easier
