Gaskets are designed to perform many different functions. Sanitary gaskets are available in many different materials to meet chemical compatibility and temperature requirements. Metal-detectable gaskets are especially useful in the food processing. Screen gaskets provide the added benefit of filtering particles in-line. Sock screen gaskets are similar to standard screen gaskets, but the increased surface area allows for extended run time between cleanings. Smart gaskets have ports that allow for taking measurements or samples from the process line.
