A patented metal-free, high-pressure sealant alternative for API-MODIFIED. RUN-N-SEAL ARCTIC contains graphite and other non-metallic, inorganic, anti-wear additives blended into a low temperature capable base grease for easier application base grease. It contains a large volume of solids enhanced by a higher concentration of large-sized particles. The improved distribution of particle sizes and volume of solids provides an excellent seal in large and small diameter, non-shouldered threads. The anhydrous calcium grease also has excellent inherent water resistance. Ideal tubing connections - 8-round and non-shouldered.
