Managed to find out the thread size for both ends of the torch used to make the bottle filling adapter but not on this site!!! so no thanks to anyone here because no one actually helped me!! M14 x 1.5 & M8 x 0.75.

Before anyone starts to send messages to slag me off I should tell you not to bother because I will not be logging on again so I will not see them.

Good Bye and thanks for nothing.
