Type 9 problems

[Big Kahuna]

BK,
I see what your saying if it wasnt lined up right, it would pull and expose the oring, but with no oring there, its not going to seal no matter what. I put the pipe on without the coupler and it appears to line up. My thought is that with no oring, the pipe just vibrates on that connection and the gases just keep putting pressure on the coupler. and a combination of both is whats causing it to fail. I forgot to take a pic yesterday, but basically the coupler appears fine except on the side next to the hull. In that area there is probably a 1inch long area by 1.5 inch area in the middle of the coupler where there is 4 different jagged tears pushed outwards at the tears. The largest tear is approx. 1/4 inch long if that.

without the o-ring there is nothing to prevent the hot gasses from burning through the coupler. First Dry pipe we installed on a buddys SJ came without the oring, we thought, hey, we will just try it, I think we even tried some RTV silicone on it. It lasted about 5 minutes.

I can see where a little high temp silicone could help, though I have yet to try it. Does it not make clean up harder though? In any case, as others have said, take the time to line the pipe up good and you will thank yourself for it later.
