I just stated putting my new setup together with camlocks for all connections. I read about some camlock orings being tight and to leave them clamped overnight to set the gasket. Well, they've been mated together for over a week, and even with olive oil on the arms of the female to reduce friction there are marks being left on the male. Is this normal? I know it shouldn't be a problem as its not on the surface of the gasket, but it seems like excessive wear.
