It ensures full injection of lubricant and reduces buildup inside the tube High-Speed Injection: Connect to an air source, pull the trigger for fast, non-jamming greasing at 9.7 g/s. This pneumatic grease gun reduces effort, enhances work efficiency, and allows precise control of grease output to maximize grease utilization Reliable Sealing: A dual-sealing systemcomposed of an explosion-proof carbon steel tube and an o-ring piston ensures a tight seal from the gun head to the tub under high pressure. This design of our air grease gun keeps hands and work conditions clean Full Compatibility: This grease gun includes an 18-inch hose, a metal bend pipe, and two flat nozzles
