Sealube Hyperbar Marine Grease CS2 (likely the GulfSea Hyperbar CS2), is a heavy-duty, multi-purpose calcium sulfonate complex soap-based grease designed for severe marine, industrial, and off-highway applications, including wire ropes, winches, open gears, chains, and bearings, where protection against water washout, wear, and corrosion is critical. Its exceptional water resistance and high-performance extreme pressure (EP) properties make it ideal for components exposed to water, shock loads, and heavy conditions.
