Tool to expand thin polyethylene tube to add flange

[win-winn]

I would like to use 4 mil wall polyethylene tubing to line a process hose with sanitary flange couplings. Need a simple way to expande the ends to fit over the flange fitting to create a seal.

4 mil, or 4mm?

is this the kind of thing you are thinking about?

As the previous poster asked, 4ml is pretty thin..
