The gaskets can be treated as a part of the fixed thread then. Give a 1 cm thickness for water film and analyze it. If you think the water wight makes thinks more difficult, fill the 1 cm gap with gas. Doesn't your calculation give a net torque again, if the total angle is not multiple of 360 ? There is a problem here too.
