I'd probably do PVC, its a lot tougher

thats exactly what i made

i drilled, and then threaded the pvc tube and then you can just screw the barbs in with some PVC glue on the thread and you're leak proof, BUT you will need a 1/2in thread to be able to thread them, but you can probably just glue them in

PVC tubing isn't clear, but it is thicker and easier to work with, if you want clear tubing, i've seen clear central vacuum tubing but i couldn't actually buy any for my project
