Produktdetaljer

SW boss is a special fitting used to create branch connections in a piping system. The SW boss is designed to connect smaller pipes or nozzles to larger main pipes by welding. The “boss” refers to the raised or reinforced area around the socket that provides additional material and strength to the connection, making it suitable for high-pressure applications.
