Features
For a total watertightness of streaming water, only PAMETANCHE can validly be selected.
These plugs enable, from their design, to continue to provide the safety function even with the presence of foreign matters in the articulation box.
Indeed, the foreign matters can be evacuated through a double lip by the action of the hinge at the time of the opening and the setting in safety position of the cover.
