The DPM-DS (Double Shoulder) connection is a generic API double shoulder connection which is widely used throughout the oil and gas industry in extended reach drilling. The DPM-MT (Master Torque) connection is an enhanced DS connection with additional 25% torsional strength, allowing clients to drill the most challenging wells.
