Second stage plug tool

Scubapro housing plugs always need a 1/4 of a turn to put them into place or take them out of the housing during service, the use of this tool will make this job a piece of cake.
 
First open de regulator cover with the cover tool after removing the mebrane then turn the housing plug with the tool 1/4 of a turn and push it from the inside out of the housing.
