Run-N-Seal® Extreme

Metal-FreeThread Sealant

Run N Seal Extreme

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. It sticks to wet and oily steel, ensuring the compound will not wash off threads.



RUN-N-SEAL Extreme is recommended for use on OCTG connections, API connections and subsurface production tools. RUN-N-SEAL Extreme will lubricate, seal, and protect threaded connections of oilfield tubular goods on makeup, in service and in storage.


For premium thread designs, use JET-LUBEĀ® SEALGUARD . For an environmentally friendly premium thread compound, use JET-LUBEĀ® SEAL-GUARD ECF.
