Ordering Hammer Union parts, Crossovers, or Integral Fittings can be complicated at times. Sometimes there is confusion when trying to identify which connection your customer needs. This confusion often leads to returns and exchanges.
In the field, especially on the industrial side, the connection with the ACME threads is typically referred to as the Male Half/Male Sub. However, it is just the opposite. The diagram below will help you and your customer distinguish which part is needed. When purchasing Hammer Union parts from C&C please be sure to indicate exactly which parts are needed. C&C does not sell Hammer Union Halves; rather we sell individual parts (i.e. Female Sub, Male Sub, Nut/Lug Nut, Snap Ring, Segments, etc) and complete Hammer Unions.
