On bearing housings or other mechanical components, grease fittings—also called grease gun zerk fittings or grease nipples—serve as lubrication points. Their design enables precise grease delivery into bearings and other moving systems by establishing a safe connection to a grease gun coupler. Externally, safety vent fittings and safety zerks resemble regular grease zerks. However, they also have a machined vertical groove in the threads, which is an added benefit. While grease is put into a mechanical component, this slot acts as an air vent. The grease will flow out when enough is applied, which also as visual assistance.
