why not flare the end of the copper tubing, and attach a flare fitting with
a hose barb.

I have a widget that has some tubes coming out. Tubes are hard copper
~1/2-inch O.D. actual. I want to attach plastic tubing to the copper
tubes. I would like to create beads in the copper tube. Copper tube
can not be removed from widget.

Can anyone suggest a method to create a bead or an alternative?

TIA
