Configurable manifold system

A manifold system comprising:

• a plurality of manifold blocks, wherein each block of the plurality of manifold blocks comprises:
• a tubular body extending between a first end and an opposite second end to define a first fluid passageway having a first flow axis, the first end having a first female union defined by a first mounting flange and a neck that extends from the first mounting flange in a direction along the first flow axis toward the second end of the tubular body, the first female union defining an opening to the first fluid passageway of the tubular body at the first end, and the second end having a male union defined by an annular flange and a tubular connector that extends from the annular flange in a direction along the first flow axis to the second end of the tubular body, the male union defining an opening to the first fluid passageway of the tubular body at the second end, the male union further comprising a gusset;
• a second female union defined by a second mounting flange and a neck that extends from the second mounting flange in a direction toward the first fluid passageway to define a second fluid passageway in fluid communication with the first fluid passageway and having a second flow axis oriented transverse to the first flow axis, the second female union defining an opening to the second fluid passageway of the tubular body in fluid communication with the first fluid passageway;
• and
• the first female union and the second female union each comprising an annular wall having a plurality of indexing features formed therein, at least one of the plurality of indexing features configured to receive the gusset of the male union to enable each block of the plurality of manifold blocks to be rotationally incrementally indexed relative to each other.
