NOTE: Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Sanitary fittings are used in the food, beverage, biotech, pharmaceutical, and other sanitary process industries to transport fluids through pipe lines and are available in a range of materials, finishes, and shapes. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
