A Top Sub, or Crossover Sub as it is sometimes called, is used to attach the motor to the drill-string.
The crossover Sub typically has a standard API box connection that connects to the drill-string and a proprietary pin connection that connects to the motor.
Top subs may also be designed with a float bore for those applications that may require Float Valve.
Optionally, a dump valve sub can be used in place of the top sub.
The dump valve sub has the same function as a top sub, but instead contains an internal bypass valve that enables the fluid in the drill-string to drain out when the string is pulled out of the hole.
