A grease nipple, also known as a grease fitting or a grease zerk, is a small device used in machinery to allow lubrication with grease. It is commonly found in various types of mechanical equipment, such as automobiles, industrial machinery, agricultural machinery, and other mechanical systems.

The grease nipple consists of a threaded metal fitting with a small ball check valve or spring-loaded ball inside. The fitting is attached to a hole or a channel that leads to specific parts of the machinery where lubrication is required. Grease is pumped into the fitting using a grease gun, which forces the lubricant through the check valve and into the designated area, providing adequate lubrication to moving parts, such as bearings, bushings, and joints.

Regular greasing through grease nipples helps reduce friction and wear, leading to smoother operation, prolonged equipment life, and better performance of the machinery. It is essential to follow the manufacturer’s recommendations regarding the type of grease and the recommended greasing intervals for each specific application.
