    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.


    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.

    Primed in greenhouse

    I set the greaser and the grease in the greenhouse for a few hours to prepare for initial prime. It primed fast with very little pumping and thumping on the floor due to hot grease and hot machine. I think my backhoe and loader bushings will last much longer because I will not put off greasing due to hassle of regular grease guns. I think if you price out the cost of replacing bushings compared to the cost of the LOCKNLUBE G.Gun Greaser, it is a good investment. I set it on a car wheel dolly to roll around the shop.

    Best grease gun.

    The best manual grease gun, small enough to carry around, but big enough for big jobs, without the hassle of reloading!

    Locknlube feedback

    I really like the unit. It moves a lot of grease fast and making maintenance a breeze. I especially like the locking nipple. I have showed it off to several of my friends with multiple machines to maintain.

    So far so good. Speeds up the greasing process, and is great for breaking free some of those harder grease zerks. Took a little while to get it primed the first time, but working fine now.
