So to clarify, until the “real plumbers” chime in, are you just replacing the portion of P-trap that was under the drain.....but keeping the other half of the original P-trap (still glued to the grey tank waste pipe) and just screwing them together? If yes, that “might” be the problem since sometimes P-traps don’t mate well if mixing brands etc. Since the mating surfaces are a compression fitting (the tapered flange fits exactly into the matching channel in the mating half); they must be mated fully; no “slightly off” pipe alignments allowed, or leaks may result. Tightening the threaded ring too much to compensate for a slight misalignment (or just two halves that are not meant to seal together) might crack your fittings. The threaded coupling is just keeping the compression faces together tightly.....unless they are slightly misaligned in some way. So not sure if it is the trying to mate two slightly dis-similar halves; or if they are just not perfectly aligned causing the leak? You have the mated half of the new P-trap......but would have to install it (PIA) and maybe could still wind up with a slight misalignment. Could try pipe dope on the mating tapered flange area to see if that would seal since the water is not under much pressure. Not sure how long that would last or if it would even work. You can probably buy P-traps that come with a gasket (high end units probably); doubt that trying to use a gasket in your existing situation (if it did not come with one) would help; might make the leak worse.
