JetLube KOPR-KOTE® is the copper-based drill collar and tool joint compound built to solve one of the most costly problems in rotary drilling: preventing downhole makeup on API rotary shouldered connections before it destroys shoulder faces, joint efficiency, and your day.

KOPR-KOTE's solids package — copper flake, graphite, and natural extreme-pressure additives in an aluminum-complex petroleum-fluid base — works differently from conventional lubricants. Instead of reducing friction uniformly, it increases the coefficient of friction under compressive load, so as makeup stress rises, resistance rises with it. The result: shoulder faces seat cleanly, standoff is eliminated, and connections ...
