Grease nipple fitting

The grease nipple, also known as the pressure filling cup, is one of the simplest ways of mechanical lubrication. It is divided into: straight-through pressure injection cup, joint pressure injection cup, and screw cap pressure injection cup. It is used to play a connecting role between the grease gun and the mechanical equipment.

The grease gun should first be connected to a hose or a hard pipe, and then the pipe should be connected to the flat nozzle, and the flat nozzle should be connected to the butter nozzle, and the other end of the grease nozzle is a thread, which is screwed on the mechanical equipment.
