Yeah, I don’t think that works because the tolerances are so little.the groove doesn’t look like it will accept one much thicker though so that may not be an option
My exact issues after a while. They were installed ok but my filter was on one of those pre-cast pads and that settled after a few seasons making the pipes just a hair off from plumb. The tight side would flatten if i tightened it to much and that’s where I learned to start loose (snug) and have a better chance of finding the sweet spot.Due to the offset angles of the original install, I had to rely on tension to square it up rather than putting a relaxed fit together and just snugging it.
