The reducing cross also is called unequal pipe cross,it is the pipe cross which the four branch ends are not in the same diameters.Just like a unequal tee,the reducing cross connect the pipes of different diameters.
Since the pipe cross has four ends,when describe a reducing cross people should indicate all the four ends diameters and their positions,or else it may bring som misunderstanding.
