Obviously the correct method would be solvent. But, I have had leaks on solvent bosses.

And I have in the past, used ct1. The stack wouldn’t stop flowing from above, getting everything wet and making solvent impossible. Ct1 can go on wet surfaces. It sealed perfectly.

If you can get it on, highly recommend using a boss with a strap around and rear clamping bolt.
