Gland
A gland is a device used to prevent leakage of fluids or gases by providing a tight seal. In the maritime context, glands are commonly used in the propulsion system of ships to prevent seawater from entering the engine room. The gland is typically located around the propeller shaft where it passes through the hull of the ship. It consists of a series of rings that are compressed together to form a seal around the shaft. The rings are lubricated with oil or grease to reduce friction and wear. Glands are an important component of the propulsion system and require regular maintenance to ensure proper function.
