NCS-30® is a premium quality, nonmetallic compound containing carbon based fibers and additives, and other natural extreme pressure and anti-wear additives. These are blended into Jet-Lube's high temp calcium complex base grease. This base grease offers the additional advantage of superior adhesion to wet steel surfaces, resistance to water wash-off, and most drilling muds. It's especially effective for invert or high-pH muds.

NCS-30 is formulated to prevent excessive circumferential makeup by increasing the coefficient of friction under compressive forces. As stress levels rise above 50% of yield, the friction factor increases, limiting downhole makeup. Full hydraulic joint efficiency is maintained allowing joint shoulder faces to mate completely without standoff or deformation. NCS-30, with frictional properties similar to KOPR-KOTE®, has been designed to utilize the makeup charts in API RP7G multiplied by its 1.15 friction factor on API connections.

• Designed for optimum performance on all rotary-shouldered connections such as Tool Joints and Drill Collars. It can also be used on premium/proprietary thread designs such as Double-Shouldered, Wedge Thread*, and other types of mechanical seal designs. It may also be used on certain non-interference tubing thread designs when properly torque compensated.

Note: For a “Yellow”-rated product, use NCS-30® ECF.
