The H-7 is a metal single joint used in the assembly of the HJ-7 joint set. The resulting joint set is the grouping of two H-7 that allow you to cross two perpendicular pipes one above another.
This single joint, when grouped with another one of its kind, will form a closed circuit for the two pipes.
