G.Gun Grease Gun - 10,000 PSI Foot Operated

SKU: GG80004

52 reviews
  • Develop over 10,000 PSI without batteries
  • Patented pressure return valve easily clears pressure from the hose and returns it to the canister with no mess.
  • Includes the LockNLube Grease Coupler, 10 ft. hose, and the G.Scoop to easily and cleanly refill with bulk grease
  • Industrial strength. Built and tested for the toughest environments.
  • Cut grease costs in half by using bulk grease. Includes the G.Scoop - the fastest and cleanest way to move bulk grease




    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.

    • All moving parts submerged and lubricated by the grease, lasts a lifetime.
    • Large canister allows regular greasing without endless refilling.
    • Pressure return valve and standard LockNLube grease coupler prevents grease wastage at the grease fitting and easily returns residual grease to the canister, saving you on grease costs and cleanup.
    • No external power required. No flat batteries or costly replacement batteries required.
    • Moving parts create wave action in grease, eliminating air locks and the need for a messy follower plate.
    • No troublesome seals to replace – any bypass which may develop, simply returns to the canister.
    • Clip-on lid keeps rain and dust out.
    • Carry handle hinges away for easy filling.
    • Balanced and easily portable.

    Foot operated grease gun

    The grease gun works great and I didn't have any trouble priming it. I put a substantial amount of grease in it to start with figuring that the more weight in it the better when I started tamping the shop floor and it primed in about 45 or 50 pumps. I really like not having to constantly put a tube in it about half way through a daily grease up like my electric model and more grease is pumped per stroke. I find that I use more grease also...and thats a good thing ! Especially on my excavator.

    Absolutely Love it

    Great. Primed easier than the video I watched. Greased just about every zerk I had. Around 100 between my backhoe and skid steer. Never leaked from the zerk but did leak slightly from threaded portion. I will say this leak was minor, and also because I was trying to force grease into pivot points that just needed to be cleaned. It is everything they say. Instead of wasting half the day go grease I can be done in 20.

    Even better than it looks!!!

    On our farm we like this better than our air powered greaser and our Milwaukee. It has great pressure and moves lots of grease fast. You can go to fields and not be switching tubes or dealing with dead batteries. The lift pressure release is super nice and if you have a stuck fitting you can pressurize the hose and get in the machine and move it to help unclog it. We simply couldn’t be happier with the grease gun and it’s our favorite!

    Foot operated grease gun

    Great find, would recommend to anyone using a quantity of grease on equipment on a daily basis. I needed it for an excavator and dozer. To much for battery operated or hand operated grease guns. Thanks

    Great Product

    Watched the video on loading the gun to get all the air pockets out of it. It was even easier than the video portrayed. It has taken all the aggravation out of greasing my equipment in the field. I was going through 3 tubes of grease getting my excavator greased and changing tubes and priming each time was very frustrating. My only regret is I didn't buy this sooner.
