Better Boat Marine Grease Tube 14 oz — Waterproof High-Temp NLGI 2 for Trailer Bearings & Grease Guns

Better Boat Marine Grease Tube (14 oz) is a waterproof, high-temperature NLGI 2 lubricant designed for trailer wheel bearings, hitch balls, marine fittings and grease guns.

Keep moving parts protected in salt, fresh water and road-splash conditions with a blue lithium-based grease formulated to meet ASTM D4950 GC-LB standards. This 14-ounce cartridge delivers long-lasting protection, resists washout and stays pumpable in grease guns so you can service trailers, boats, ATVs and light equipment with confidence.

How does this grease protect trailer bearings and hubs?

The formulation provides adhesive film strength and mechanical stability that reduces metal-to-metal wear under pressure. Its NLGI 2 consistency keeps the grease in place inside bearings and seals while the waterproof additives minimize corrosion from water exposure.

• High film strength and adhesion for extended bearing life
• Waterproof additives to resist washout and salt spray
• Meets ASTM D4950 GC-LB for trailer and wheel bearing use
• Compatible with typical bearing seals and raceways

Will it work in a grease gun and with other fittings?

Yes — the 14 oz cartridge and formulation are compatible with standard grease guns and fittings, so you can push grease directly into zerks, hubs and fittings without messy transfers. The consistency stays pumpable across a wide temperature range for reliable application.

• 14 oz cartridge fits most hand and lever grease guns
• Pumps cleanly into grease zerks and wheel bearings
• Stable consistency under varying temperatures
• Also available in 3 oz for small jobs or tight spaces

How does it perform in wet or high-temperature environments?

Better Boat grease is engineered for marine and roadway conditions, resisting water intrusion while maintaining protection at higher operating temperatures. This makes it suitable for trailer use year-round, from freezing mornings to hot summer hauls.

• Waterproof formula minimizes corrosion and washout
• High-temperature stability prevents breakdown under load
• Suitable for saltwater and freshwater exposure
• Blue lithium base simplifies visual inspections

What materials and equipment is this grease compatible with?

The grease is formulated for universal service on automotive and marine components including wheel bearings, hitch balls, pivots and light-duty machinery. Because it meets relevant industry specs, it works with common metals, seals and bearing types used on trailers and recreational vehicles.

• Wheel bearings, hub assemblies and spindle bearings
• Trailer hitch balls, couplers and pivot points
• Marine deck hardware and small machinery requiring grease
• Compatible with common elastomer seals and metal fittings

Who is this for? Boat owners, trailer service technicians, RV and ATV enthusiasts, and anyone who maintains wheel bearings or marine fittings will benefit from Better Boat's waterproof NLGI 2 grease. If you need a reliable, gun-compatible lubricant that resists water, holds up at temperature extremes and meets ASTM D4950 GC-LB performance, this 14 oz cartridge is designed for routine maintenance and seasonal servicing of trailers, boats and light equipment.
