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.
