I wanted to make something like that with a chain pull so you can localize the purge around the weld area but couldn’t figure out a good diy solution to make the stoppers fit the inside of different tube dia’s, without having different dia purge blocks for each case.

don’t waste your time, just buy one. Mine are from WeldWide([http://weldwidesolutions.com/products\_inflatable\_purge\_dams.html](http://weldwidesolutions.com/products_inflatable_purge_dams.html)). I have a 2" modified to work in 1.5" to 2", and a 4" modified to work in 2.25 to 4".

For short pipes, just use taperd rubber stoppers in the pipe ends. Easy to get at any plumbing store. Drill 1/4" hole in one end, run airbrake tubing to argon tank and reg, ~5cfm or so pending how many joints there are(more joints, more cfm leakage)
