grease fitting

A metal connector installed on bearings or other mechanical components to provide lubrication points for feeding lubricants without overflow or leaks. The fittings should be kept closed to block contaminants until the pressure from a grease gun forces them open, allowing grease to flow to bearing. Also called zerk fitting.
