Elesa has released a tank filler cap for hydraulic systems, with two selectable modes to accommodate transportation and use of the equipment. The SFC operates as a standard filler breather and provides for high-volume oil flow in the first mode, with guaranteed high airflow to compensate as the tank fills/empties rapidly.

Mode two is achieved by rotating the cap clockwise on a quick turn thread and this clamps the cap down onto an 'O' ring, making a complete seal which prevents breathing and more importantly loss of oil during transportation.

To open the cap for breathing again, the quick turn thread is turned anticlockwise.

If turned past the quick turn thread (not easy to do by mistake) the cap may then be screwed completely off to gain access to the filter medium for cleaning if oil has splashed into it during movement.

By providing both features in one 30mm cap mechanism, Elesa has offered users of off-road or transportable equipment a further aid to safety and convenience in day to day operation and maintenance of their hydraulic systems.
