Grease fitting by Wikipedia Bot 0
A grease fitting, also known as a grease nipple or zerk fitting, is a small mechanical component typically made of metal that allows for the easy application of lubricant (usually grease) to an assembly, such as machinery, automotive parts, or various mechanical linkages. The fitting provides a convenient and effective way to ensure that moving parts are properly lubricated, reducing friction, wear, and the likelihood of breakdown.
