Mr.Master Pre-filter Lid

The Mr.Master pre-filter lid is the closing element of the pre-filter housing of a pool pump, which allows quick manual access to the filtration basket for its removal and cleaning. The transparent design of the lid (where relevant) allows visual inspection of the basket’s condition without having to remove the lid. The lid seal ensures the watertightness of the joint under operating pressure. A damaged or cracked lid must be replaced immediately to prevent water leakage or air suction. The original lid matches the exact thread and diameter of the Mr.Master pre-filter housing.
