Adapter RH/Q Adds Versatility to your RH head by adapting it to any Q pump drive. This is a complete adaptation system that permits use of an RH miniature pump head on any Q drive module. Once the RH pump head is fitted (3 screws) to the kit parts, it can be slipped into place on the drive module in seconds without tools. To remove it, simply loosen the two thumb nuts of the motor base and slip it off.
