I posted in another thread but I thought I would get better results here..


Ok just got a full collector tank setup today (bottom) the old one is (top of pic) both measure the same but I can't get the new one to tighten down all the way. Looks like its missing the inside shoulder to go over the o-ring. If you can see in the pic the threads on the new one come all the way to the end. (Old one on right, new one on left) Anyone else have this problem?
