Ah ok. I was just wondering because I'm thinking of making myself a custom reservoir. I guess I'll just buy some acrylic tubing.
Lots of superglue and wishfull thinking?? J/K.. My best guess would be some sort of bondable caulking.. slap some of that on the seam and than use those insanely big hose clamps to close it shut and wait for the bond to form..
My second guess would be to use the hose clamps to close the gap and heat the seam up so it melts together???
