Rotalock Valve Leak

Found the discharge valve had become loose over time, replaced the gasket and put some mid strenght thread lock on the fitting to help prevent it happening again. The loosening is due to the movement of the compressor on starting and stopping and alos the pipework layout. Its not helped in this case by the brass male fitting as opposed to the more common steel one. Steel on steel seems to grip better and even a little rust can be our friend in this instance.
