The G. Gun patented pressure return valve, takes 10,000 PSI from a 10-foot hose and returns it to the canister with no mess. The pressure drops to 0 PSI in an instant. To avoid leaks and mess when dealing with clogged fittings, this is the best grease gun on the market. 

In this video Jay jumps on the foot pedal with both feet and the G. Gun keeps pumping up to 10,000 PSI. Our lawyers told us that we need to tell you not to try this at home! If you hit a clogged fitting that you can't clear, lift up o nthe foot pedal and try clearing the fitting with Grease Buster Tools

The LockNLube Grease Coupler plus the G. Gun is the toughest greasing system out there.
