How to do a Capillary "T" Seal #5

Last (close window) Next


With a wide flame, heat both the hole in the side of the base tube and the end of the “T” tube. Once the edges become juicy, stick the pieces together. Using a narrow flame, work the four sides of the seal till the folds are fused closed. Take your time when doing this so as to not get the base tube so hot as to loose it's regidity and cease to be a straight base tube. OR work so fast as to not give the base tube time to become soft.
