Bill,

 

            One solution that has worked for me;  drill 4 to 6  1/8” holes in a circle around the end of the tubing.  Around 3/8^th up from the end of the tubing and evenly spaced.  Squeeze 1/8^th dome head rivets in the holes.  (Dome head to the outside of course). 

 

            Along the line of Ed’s solution is to get a welder to weld a bead all the way around the tubing.  In practice I have found that a full bead isn’t really necessary but that a bunch of bumps serves the purpose.  Hence the rivets.  At least on water connections that I have done this on.

Dave’s number 4 below brings up a question I have been pondering.

 

How do you put a bead on the ends of aluminum tubing so the hose will not slip off???

 

My tubing is inch and a quarter and probably 0.060 thick.  Suggestions appreciated.

 

Thanks,

Bill B
