To help maintain solvent purity, our safety caps with integrated evaporation control include replaceable threaded particulate filters above the valve. These filters are supplied in various colors to identify the valve seal material of the cap (blue for EPDM, green for FKM, and yellow for FFKM).

Purchase colored spares as needed or replace on a schedule. A plain white option is also available. All filters are made from 50µm polyethylene and are supplied in packs of four. Please note that these filters are not intended for submersion in solvent or for sparging applications.
