Brushable, environmentally preferred, lead-free compound specifically designed for percussion drilling. J-75's highly fortified formulation provides excellent resistance to shock, galling and seizing. Its anti-friction properties are unsurpassed while providing easy thread assembly and disassembly. Under makeup pressure J-75 lubricants “plate” and form a tenacious armored coating that eliminate metal-to-metal contact while penetrating voids, surface imperfections and score marks to increase thread life on steel bits, joints and couplings.
