Description
U-Lube Cartridge - 3oz. *2-Pack U-lube is a long lasting waterproof grease specially formulated to lubricate and protect internal ball valve components, and to discourage nuisance marine growth.
U-lube's tacky texture keeps it where it is applied, and helps provide maximum protection against wear, rust, and water washout in non-ball valve applications such as bushings and bearings exposed to wet conditions and a wide range of temperatures. For ball valve applications a zerk fitting replaces the drain plug, enabling U-lube to be injected into the cavity between the valve body and the ball while the valve is in the OPEN position.
The approximate volume of grease required to fill GROCO ball valves and the grease volume for other valve brands will be similar. Features: Size: 3 oz.

Marine Plumbing & Ventilation — frequently asked
- How do I size a bilge pump?
- Bilge pumps are rated in gallons per hour (GPH), but actual output is lower once you account for hose length and vertical lift. Choose a pump rated well above your expected worst-case water intrusion, and consider a second, higher-capacity pump plus a float switch for automatic operation.
- Can I use regular garden hose for my boat’s water system?
- No. Marine plumbing uses purpose-built hose rated for the specific system — potable water, sanitation, and raw-water/bilge hoses differ in pressure rating, temperature resistance, and permeation. Using the wrong hose causes odors, leaks, or contamination.
- Why is ventilation important on a boat?
- Ventilation clears moisture that causes mildew and rot, and — critically on gasoline boats — clears fuel vapors from the engine compartment before starting. Blowers, cowl vents, and dorade boxes keep air moving through cabin and engine spaces for safety and comfort.
