PVC leak-free joints without glue

jointspvc

I am interested in installing a PVC tubing conduction (80 mm diameter, no longer than 1 m.), with two 90 degree joints. I would like to know if there is a way to fix the joints without the use of glues of any kind, instead I am interested in mechanical methods like o-rings or threads, the conduction will not be under pressure and it will not conduct water at full capacity, it will conduce a small amount of cold water.

You could probably use Flex Couplings like these:

To connect a pipe to an elbow, you'd have to find a coupling which fits both the outside diameter of the pipe, as well as the outside diameter of the elbow.
Something like this one might be flexible enough to both stretch over the elbow and still clamp tightly onto the pipe:

or otherwise possibly one of the reducing versions which have a different size on each side.
