I think that it will be a little loose, but the solder will turn around appropriately. In order to avoid the formation of an oxide film inside the piping in case of himself make a cut 3 mm in the neck of the center part of the product, put the reducing air of the gas through the hole, prevent oxidation as much as possible, I plugged the hole with solder. It is easy to paint flux on the joining part of the pipe like a knack. If possible, it is decided that it is better not to extend the piping, but basic piping from the beginning can be used for wall embedment and so on. Good results have been obtained with vacuum drawing.
