Transparent in-line filters with 50 mesh stainless steel screen. These filters are designed to screw directly onto the inlet side of 1/2" threaded pressure pumps. They can eliminate unnecessary pump repairs by keeping debris and particles out of the pump. Easy screw-apart disassembly for cleaning. All have 1/2"female thread to screw onto the pump - and 1/2" male thread or 12mm hose barb inlet.
