Metal-Free Thread Sealant RUN-N-SEAL EXTREME 50 Gal. Drum of Jet-Lube is 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. Benefits of using Run-N-Seal Extreme Enhanced rust inhibiting properties Contains additives for protection against rust, corrosion & oxidation Prevents leakage (seals to 10,000 psi) High film strength H₂S Inhibited Sticks to wet & oily steel, ensuring the compound will not wash off threads Specifications Base Materials: Complex Soap / Petroleum Friction / K-Factor: 0.9 (Relative to API-MODIFIED) Certifications: Exceeds all of the performance criteria described in API spec. 5CT, Tested in conformance with API RP 5A3 TDS SDS
