Which glue for gluing PVC and PET together?

Hard mode: can be found in Yurop.

for what purpose? a rubber sleeve and a band clamp will work. pvc is notorious for not being gluable. they use blue goo for downpipes and green goo for pressure pipes. the green goo is a solvent that melts the pipes together.

I would suggest melting the pvc pipe so that it has a ring around it you can apply a clamp to and using a piece of rubber hose or rtv silicone to form a gasket, apply the pet tube, wait for it to dry then clamping it.

Actually, PET is the difficult one. From what I've seen online you usually need to add a primer to it first for the glue to work.

OP here. So far I found that cyanoacrylate (instant glue, super glue) works pretty well and better than a couple of others I tried. Not sure how it will handle some moderate flex, we'll see.
The colored glue used for PVC tubes is worse (doesn't stick to PET much), but maybe it could be good enough as well.
Some epoxy two part glue was the worst.

Polyethylene is a chemical resistant material and therefore most solvent cements and epoxies will not react with it or adhere to it. I'd suggest fastening them mechanically if possible

Polyethylene shrinks with heat, so that might not work well.

As a guy who has actually done this, hot glue, the PET will shrink slightly.

Just a little reminder:
PE = polyethylene
PET = polyester

They have rather different properties.

From your article:
>In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym PET is generally used in relation to packaging.
You could also compare the contents of that page to PE's:
