The Jabsco bilge strainer 46200-0000, 19 mm (¾ inch) Pumpguard is a filter to protect bilge pumps from dirt and damage. The dirt filter prevents bilge debris from clogging the suction hose and reduces the risk of debris entering the pump and blocking it. The filter has a 40 mesh (0.4 mm) stainless steel filter screen which can be easily and quickly checked and cleaned using the transparent screw cap. The filter has standard hose connections for easy installation on ¾ inch hoses.
