JLS®

Tool Joint Compound

JLS is a high-quality product containing premium grade copper flake, amorphous graphite, rust and corrosion inhibitors, and other inorganic solids. All are blended in JET-LUBE’s unique grease compounded from custom refined, low-sulfur oil to ensure brushability over a wide temperature range, tenacious adherence to all surfaces, resistance to water washout, and prevention of rust/corrosion.

JLS is a result of laboratory and field development efforts spanning several decades. It is manufactured under the industry’s toughest quality control regimen and is especially designed to prevent thread and shoulder wear, and to provide superior performance on the rig floor and downhole in medium duty drilling just as KOPR-KOTE and 21 perform in more severe conditions. For inverted muds or high pH muds use 21 or EXTREME.

APPLICATIONS:
Recommended for use on tool joints in drilling medium depths and formations. It provides consistent control of makeup and break-out in these conditions and protects against galling and seizure. JLS prevents excessive stresses which shorten tool joint life, and the metallic solids of JLS form a gasket on threads and shoulders that prevent metal-to-metal contact under high torque loads.
