The grease nozzle is the easiest way to mechanically lubricate the oil cup. Divided into: straight-through injection oil cup, joint type injection oil cup, screw-type injection oil cup. Used for connecting between grease guns and mechanical equipment.
The grease gun must first be connected to a hose or a hard tube. The top of the tube is connected to the flat nozzle. The flat nozzle is connected to the grease nozzle. The other end of the grease nozzle is threaded and screwed onto the mechanical equipment.
