Re: Meg cold diving - QC4 leak

Tibby, have you pinpointed the location of leakage encountered? Was it male or female part, or internally after assembly? Pressurized or unpressurized? There are many variables to consider here.
In my opinion, the source of the leak is the o-ring housed in the female part which seals onto the shaft of the male side when connected (under pressure of course). I think what happens is that this o-ring gets stiff from the cold and if the male part has room to move inside the o-ring (excessive tolerance) then a leak occurs. The connector did not leak until I moved the male connector but then it got worse and worse.
