I have a propane regulator (airbrush type) and want to connect it to 4mm polyurethane pipe (as provided by Jet cat). The fitting on the regulator is 1/8bsp (I think).
Can anyone advise me how to go about it the simplest way.

Thanks in advance from Scotland

You need to either warm the clear tube in a mug of hot water and struggle to get it over the thread (it will go)

Or remove the nipple and turn it down in a lathe.

Thanks for the info Dave.
I'll try the former but if I mess it up I'll get hold of Motors and Rotors for the pucka piece.
