AquaShield is a multi-purpose lubricant and sealant that is compounded specifically to cling to metal and "O" ring surfaces, provide long term lubrication and rust protection. It is designed to seal out water and contaminants. AquaShield is particularly effective on bearings, water pumps, "O" rings, water filters, motors and valves that must operate in hot or cold water, steam, pool chemicals, salt water and subsea environments. Frequently used on dredging equipment, submerged or arduous environments as the grease resists wash-out.
