Run-N-Seal® Extreme®Metal-Free Thread Sealant

A patented metal-free, high-pressure sealant alternative for API MODIFIED. RUN-N-SEAL EXTREME contains graphite and other non-metallic, inorganic, anti-wear additives blended with KORR-GUARD, a high-temperature, rust-inhibiting complex soap based grease used for storage applications for nearly 2 decades. RUN-N-SEAL EXTREME 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 complex soap grease provides a high melting point, ensures brushability over a wide range of temperatures and has excellent inherent water resistance. Ideal tubing connections - 8-round and non-shouldered.
