How to load TAMISIUM solvent tank with n-butane

How do you take the tank of N-butane http://www.airgas.com/browse/product...uct=NB%20ILP5S
and transfer that gas into the tamisium solvent tank to be blasted with, no videos are ever clear on this step, and either load it with cans of unpure butane or it is preloaded before the video.

You can get the left handed POL propane valve nut assembly at a RV supply and a Dixon quick disconnect at Paramount Supply.

could you possibly supply pictures of the pieces I need, to make sure im getting the right pieces.
