The union of the connection

The Union is composed of three single pieces, namely male, female and female.

The male port is matched with the socket of the female mouth, and the other head is connected with the external thread of the pipe. The head of the female mouth is matched with the male socket, and the other head is connected with the external thread of the pipe. The outer surface of the female sleeve is hexagonal, and the inner surface is Internally Threaded. The internal thread is matched with the external thread on the female mouth.

The Union is a live interface connector, which is installed at the place where you need to remove it. During installation, the male and female ports of the Union are respectively connected with the short threads of the pipe end. The method is to first place the female sleeve on the side of the male port, and make the side of the female hanging thread facing the female mouth, and connect the male mouth and the short wire of the pipe respectively, and the connection method is the same as the short wire. Before locking the nut, add a gasket at the male port, the inner diameter of the gasket matches the diameter of the socket, then level and align the male and female ports, and then connect the male and female ports with a female sleeve.

The union connection is directional, and the flow of the medium flows from the male port to the female Port. The workers on the construction site are jokingly called "male in and female out" and cannot be reversed. The Union is an ideal movable connection.
