RUN-N-SEAL ECF is a patented metal-free, environmentally safe, high-pressure sealant alternative for API-MODIFIED on thread seal connection designs such as 8-round, buttress & DINO VAM. The compound contains unique graphite and other non-metallic, inorganic, anti-wear additives blended into a high-quality calcium complex base grease. RUN-N-SEAL ECF 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 or thread seal connection designs. The calcium sulfonate complex grease provides a high melting point, ensures brushability over a wide range of temperatures, and has excellent inherent water & corrosion resistance. It sticks to wet and oily steel, ensuring the compound will not wash off threads.
