The Single Element Sump Strainer from Buyers Products works inside your fluid reservoir to stop items from being sucked into the system and causing damage. The cleanable strainer can stop items 150 microns or larger, using a pleated element of stainless steel wire cloth (100 mesh). It has an extra large filtering area, allowing a greater flow rate. The strainer installs into the wall of the reservoir and is available in a range of port sizes and flow rates. Choose from a range of NPTF port sizes.
