• Two (2) GROCO U-Lube 3oz Cartridges

• Advanced Waterproof Formulation: A long-lasting, tacky grease texture ensures it stays precisely where applied, offering maximum protection against saltwater washout, rust, and wear, even in demanding wet conditions.
• Marine Growth Inhibitor: Uniquely formulated to discourage the growth of barnacles, calcium, and slime, preventing them from seizing your ball valves and seacocks.
• Corrosion Prevention: Displaces stagnant saltwater within ball valves, effectively combating corrosion and prolonging component life.
• Enhanced Valve Operation: Improves the ease of valve actuation and extends the overall service life of your marine plumbing.
• Versatile Application: While ideal for ball valves, its high-temperature stability makes it also suitable for lubricating bushings and bearings exposed to wet conditions.

Optimized for GROCO ball valves and compatible with other major marine ball valve brands. For older valves, consider pairing with the GROCO #ZERK-1 Zerk fitting for easy grease injection.
