Oh, you mean theyre not supposed to leak???

Mine drips a little and I just figured it was because it was old and worn. It seemed to make more sense to use the steel rings in there. I thought tightening would displace the rubber and push it out of the collar if I didnt use those rings. One thing I noticed was the old seal was quite a bit thicker then the replacement. That may have something to do with it as well. :confused:
