A stainless steel socket is a pipe fitting with female threads on both ends, used to connect two male-threaded pipes or fittings of the same diameter. It is designed to provide a strong, leak-proof connection and is often used in systems requiring high corrosion resistance and durability. Stainless steel sockets are ideal for applications in harsh environments, such as chemical processing, marine, and industrial systems, due to their excellent resistance to rust, high temperatures, and corrosive substances.
