Well, in retrospect...I should have not bothered with sealing those fittings. Because, as Jim mentions, I think those are slip fittings with grommets. I'm not sure how long they're expected to stay pliable to make a good seal. But, I got in there and wiggled the pipes and could definitely see a bit of give around those grommets. So, putting RTV around them was in vane.
