The Jet-Lube Gear Guard (MPN 17941) is a 12 oz aerosol paste-like, viscous lubricant formulated to reduce friction and wear on heavy-duty components. It contains molybdenum disulfide (MoS2) and graphite within a petroleum oil base, providing exceptional "stay-put" characteristics and maximum lubrication. This lubricant is designed for open gears, chains, cables, wire ropes, fifth wheels, leaf springs, drive chains, screw threads, flexible couplings, and die-set leader pins. It resists heat and pressure, displaces water, prevents rust, and protects against scoring, spalling, and welding of gear teeth. The black-colored lubricant has a service rating from -25°F to 350°F (-32°C to 175°C) and dries quickly to prevent contaminat
