Strainers are placed in-line with process piping to remove large solid contaminants from the flow.  Strainers can be cleaned and reused. Strainers can be supplied as either an assembly or an element. A strainer element is a simple mesh or perforated metal element that may be used as replacement or a handheld strainer. Strainers can be used in a wide variety of applications, including but not limited to: general purpose, chemical, coolant, food processing, laboratory, industrial, high temperature, high viscosity, hydraulic fluid, medical or pharmaceutical, oil or fuel, refrigerant and water.
