FRUSTRATION FREE GREASING …  NO MORE STOPPING TO CLEAR AIRLOCKS, REPLACE GREASE CARTRIDGES, AND FIGHT WITH STUBBORN ZERKS.

The unique two stage pump creates a wave action that smooths out those annoying airlocks.

This grease gun is industrial strength. Able to pump at 10,000 PSI (690 Bar). It will put grease in stubborn fittings that don’t take grease with a hand pump grease gun. This also makes tensioning excavator (crawler) tracks, in the field, a simple job.

The canister holds over two gallons of grease. That’s 20 standard size grease tube cartridges you need to replace for every one G.Gun refill. You spend a lot less time refilling or replacing grease tube cartridges and more time getting your equipment greased.

You can maneuver to get at all of your grease fittings by moving the included 10-foot hose and attaching the LockNLube® Grease Coupler that comes with every G.Gun. No need to pick up and move the G. Gun, simply pump with your foot.

INCLUDES THE G. SCOOP

The G. Scoop makes it easy to load your G. Gun with bulk grease. Quickly and cleanly scoop grease from a bucket into your G. Gun. Move pounds of grease with each scoop and cleanly stores the scoop and paddle in the included case.

After greasing with everything else, this is the best.

I have used lots of grease Guns, but none like the G Gun. It holds a lot, so I am not always changing messy cartridges like the electric ones, that are always out when you want to be greasing. It will build more pressure then any other gun for tough grease fittings, and the fact that you can release the pressure is something no other gun I know of can do. It makes getting the grease coupler easy to get off. I like that it is quiet so you can hear the grease moving a lot of the time. Filling it up is fun and not too messy if you take some time to do it right. The only thing I might warn someone about is it is a bit heavy when full of grease, so if you are in your 90's and have no upper body strength left, get a young guy to do your greasing. I think 90% of people out there will be very pleased with the G Gun, and it will still be in use by your grandkids 70 years from now.

GGun

I used it on a Cat 446 Backhoe and it made greasing much easier and less messy. The high pressure available from this grease gun opened up a few of the tougher clogged zerk fittings easily. there were a few that I had to use the grease buster tools on and they worked good also. there are only a few that need replacing.
