Liquid-O-Ring 757 Lift Boat Gear Lube is a black, extreme pressure grease with excellent water resistant properties. It offers excellent adhesive and cohesive properties. Liquid-O-Ring 757 Lift Boat Gear Lube
has a very tacky texture yet remains very smooth and buttery. Manufactured with graphite and molybdenum disulfide (moly), Liquid-O-Ring 757 Lift Boat Gear Lube forms a protective lubricant coating under heavy loads which prevents metal-to-metal contact. This lubricant has excellent load carrying capability and is very resistant to water washout. A NLGI grade 3 grease, Liquid-O-Ring 757 Lift Boat Gear Lube services temperatures from -8 (-22°C) up to 275°F (135°C) and is non-corrosive to copper and steel.

APPLICATION:
Originally designed to be used on the legs of a jack-up or spud barge, the highly adhesive
properties of 757 Lift Boat Gear Lube make it an ideal lubricant/dressing for open gears, rock-drill stems, marine ways, underwater equipment, and industrial applications where extreme resistance to water washout is desirable.
