A grease nipple, also known as a grease fitting or Zerk fitting, is a small metal fitting with a ball-and-spring valve, used to inject grease into mechanical systems. It is permanently installed into a bearing or joint, allowing a grease gun to attach to the nipple to deliver lubricant under pressure, which prevents wear and ensures smooth operation of machinery. These fittings are made from various materials like steel and brass and are available in different thread sizes, shapes, and angles to match specific applications.
