    HydroGuard™ Makes Sure That Oil and Water Don't Mix

    D-A HydroGuard™ is designed to separate and shed water in applications where water is inevitable. Whether it is a result of a working environment, such as in a dredging operation, precipitation or moisture condensation, water can get into the lower gear case of a crane's travel mechanism and contaminate the gear lubricant. When compared to conventional automotive gear oils, HydroGuard ensures protection of gears in wet applications. More info.
