PPH All Plastic Union is composed of three pieces. The left and right pieces are internal and external threads at each end. The middle piece is internal thread and internal flanging. It is a set containing a certain clearance space. The flanging part is locked with the size of the left part and can be rotated freely. The left and right (with middle part) are screwed to the pipe head respectively.
