Price is for one filter cup. It is made from a 2mm thick stainless steel sheet. It is factory pressed by template on a 30 ton punch press. It has a 6 micron stainless steel screen bonded to the bottom of the cup. This allows complete drainage of solvent while capturing debris . Most steel cups are 1mm - 1.5mm thick, but this one is 2mm of stainless steel, so it's designed to take punishment. The best placement of stainless steel filter cups is (in the tube stack) is closest to the barrel. These slide nicely into any our solvent filter tubes.
