Ian. I would suggest that leakage up stud threads is far more common than you think it is. As for gasket leakageĀ It is without doubt the composition of the gaskets. On my steamer I try to use only asbestos jointing, and have a good stock of it. But occasionally have to use modern equivalent in the larger sizes. With a smear of the graphite flake/oil paste I mentioned earlier tje asbestos can be re used time after time. The modern stuff gernerally fails at the first part. And is far less tolerant of marked lands. Its not unusual for a joint made with modern gasket to have to be remade due to leakage. Its unusual that an asbestos joint has to be remade.
