Oilfield Nonmetallic Thread Compound JET-LUBE NCS-30 Oilfield 5 Gal Metal Pail Lined 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. Ideal tubing connections - rotary shouldered, double shouldered and premium.
