If you can get a cutout to seal up, you've done something. Those gaskets suck. You could try some high $ copper gaskets if you're really worried about it sealing all the way. 
triple gasketing?

triple gasketing? Im almost done my custom e cutout set up (custom in the sense that im fitting a 3.5" QTP on my 3" cutout. It is currently double gasketed with clearanced gaskets to give the valve time to open before having to fit in the pipe but it just barely catches. So i was thinking 1 or two more gaskets will do the trick. Will running 3 or 4 gaskets cause leaking problems or anything else?

Yeah, they work about 95% leak free. Good choice. Trending Topics
