The pipe fittings with square head cored plug are components used for closing and terminating the end of a pipe. Made of stainless steel 304 to ensure higher corrosion resistance than 302 grade steel.

The cast pipe fitting has tubing connectors. It is suitable for copper, brass, aluminum, and steel tubing. The fitting can be used in fuel equipment, plumbing, gas, refrigeration, and vacuum applications. When purchasing pipe 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).
