I am slipping 1 1/4" pvc inside 1 1/2" pvc. 1/8" tape making about three wraps of the 1 1/4" works. Real o-rings would be nice tho. I have comptemplated using 1/4 x 1/4" tape and getting a tighter wipe on the inside of the 1 1/2 pipe.
The tape is laid immediately against the previous wrap, so it synthesizes a 1/8" thick 3/8" wide ring. Not a great wipe, and the resonance is not as strong as a fixed tube cut to the correct length. My hunch is some air motion or damping is occurring on the joint.
The tape slides a wee bit on the pvc, but gets support from the next wrap. A real o-ring might be a better choice.
I looked at the website, no mention of O rings.
