초록 ▼

A union for tubes having a first external wall and a second internal wall coaxial with the first to define a chamber around a central duct. The union includes at least two seats for reception each of one end of a tube to be connected. Each seat includes a first surface designed to adhere to an end segment of the first wall of a tube inserted in the seat and a second surface coaxial with the first and designed to adhere to an end segment of the second wall of the tube. Between the first and second surfaces of the union there is a connection surface. The union includes in it first ducts which lead into the connection surfaces to provide connection between the chambers of tubes inserted in the seats and second ducts which lead into spaces circumscribed by the second surfaces to provide connection between the central ducts of the tubes.
