Groco U-Lube Cartridge (2-Pack) - 3 oz - ULUBE-3

Ball valves (in-line valve or flanged seacocks) that are "exercised" frequently operate more easily and are likely to remain free of marine growth. The task of regularly opening and closing valves, however, is often neglected because valves are difficult to reach, or because owners just don't feel like it. Consequently, valves are left in one position for months or even seasons, and when the time comes to open or close the valve, the build-up of barnacles and calcium makes it extremely difficult or impossible.

U-Lube is injected through a Zerk fitting, standard on GROCO valves beginning 2016, into the cavity between the valve body and the ball while the valve is in the OPEN position.

Stagnant seawater promotes corrosion and growth of marine organisms, so neglected ball valves will naturally accumulate slime, barnacles and other nuisance marine growth. With U-LUbe the space now filled with grease, marine growth is inhibited and the valve will operate more smoothly.
