Purpose and Specifications

LIQUI MOLY Marine Grease 25044 is a heavy-duty, white marine-grade lubricant in a convenient 400g cartridge, perfect for boats and vessels exposed to saltwater and harsh wet conditions. It reduces friction and wear on bearings, hinges, and moving parts, staying effective from -20°C to +100°C for reliable performance in cold mornings or hot engines. This tough grease meets NATO Marine Specification G460 and DIN 51502 KPF2G-20 standards, offering excellent water resistance, saltwater impermeability, and long-lasting sealing to prevent corrosion and leaks.

• Key Benefits: Repels hot/cold water and saltwater completely, providing extreme durability in marine environments
• Practical Temps: Works smoothly from -20°C (freezing winters) to +100°C (hot running gear)
• Longevity: High shear stability means it lasts seasons without breaking down; reapply every 6-12 months or 5000km of use on trailer bearings
• Shelf Life: Up to 5 years unopened when stored cool and dry

When to Use / Replace?

Use LIQUI MOLY Marine Grease on all grease points like propeller shafts, steering systems, winches, and trailer bearings where water or salt exposure is constant. Apply with a standard grease gun following your equipment manufacturer's guidelines. Replace grease every 6 months in saltwater use or annually in freshwater to maintain protection; check if it feels thin, contaminated, or if parts squeak/noise after washing.

Pro Tip: Ideal for exterior parts in salty air too - extrudes easily for quick jobs.
