The invention realizes an improved sealing unit (1) for the electrolyte of electric batteries which includes a container which is closed through a cover (4). Said cover (4) is provided with annular elements (80) circumscribing the holes (3) which let the poles (2) pass by and be coupled to the elements which are housed in said container. Said sealing unit (1) includes a tubular ring nut (5) which is coupled in the interspace existing between said pole (2) and said hole (3), and which cooperates with at least a first sealing gasket (6). Said first sealing gasket (6) is included between said pole (2), said cover (4) and said ring nut (5), and realized with them an annular sealing area (61, 62, 63). |
