Drill Pipe Connection Thread Identification Ruler with Nozzle Gauge (1)

Description

1 Ruler... Every DD must have one of these thread identification rulers. Don't guess the connection type and lose a fish in the hole. It may not be your responsibility to dress the bit with nozzles but you risk letting someone else make a decision that could slow down ROP. Get this gauge and run the pressure drop calculations yourself, or you'll be dragging a dead horse through the lateral with no differential pressure.
