Groco ULUBE3 is a specialized marine valve grease designed to keep ball valves, in-line valves, and flanged seacocks operating smoothly in harsh saltwater environments. This 3-ounce tube contains a waterproof, non-toxic grease formulated to prevent marine growth buildup and reduce the effort required to operate marine valves.

Key Features:

• Waterproof formula prevents washout in marine applications
• Non-toxic and safe for use in potable water systems
• Reduces friction and operating effort on ball valves and seacocks
• Helps prevent marine growth from causing valve seizure
• Compatible with bronze, plastic, and composite valve bodies
