The LNL151 is a heavy-duty lever grease gun that delivers an ounce of grease in 28 strokes and up to 10,000 PSI. Holds 16 oz. bulk grease, or a standard 14 oz. cartridge. 20" heavy-duty hose with In-Line Swivel and LockNLube® Grease Coupler makes greasing fast, clean, and easy. 
Our “Loop & Lock” storage feature allows you to secure the coupler when not in use. It also creates a loop in the hose easily used for storage or carrying. This means no more greasy mess on your clothes, truck, and shop from loose hoses flying around when you pick up the grease gun.

    "I highly recommend LockNLube. Great product and unbelievable customer service!"

    "Best grease gun I've owned! Works exactly as described. Zero issues with priming the gun. The locking coupler works fabulously and leaves a free hand to help pump."

    "Greatest thing since the invention of the aluminum beer can ... won't own a grease gun without it"

    The LockNLube®  grease guns are the world's first leak-free grease guns. The LockNLube grease coupler will not leak when locked onto a grease fitting. When not in use, the Loop & Lock storage design keeps the coupler secured and clean.

    Our grease guns also feature an in-line hose swivel so you can rotate the hose and coupler without spinning the grease gun. We also include a 20" high-quality hose - longer than any other grease gun on the market.

    The LockNLube® lever grease gun delivers up to 10,000 PSI and an ounce of grease in 28 strokes. This rivals any lever grease gun out there. Our locking coupler means that you have both hands free to pump, and aren't using your ribs or machine to push the grease gun. We feature a one year warranty on all of our products. If you experience any problems in that time, send it back and we'll replace or refund your order.

    You'll also get a spare seal kit so that if the rubber seal on your coupler ever wears out, you can simply replace it with the spare, rather than replacing the coupler.


    LockNLube® created the patented Loop & Lock design because we know that the grease gun is part of your life, even when it isn't being used. In the past, this meant it was getting grease on everything it touched and making a mess in your truck and tool box. Now, you clip your LockNLube Grease coupler onto the storage Zerk, and you can store and carry your grease gun without the fear of it leaking and making a mess.

    They built a better mousetrap.

    The coupling device is an absolute game changer! I have snapped off so many fittings on new trailers and/or with new guns. The greases gun itself is a marvel. Solidly built WITH INSTRUCTIONS IN ENGLISH. Works exactly as advertised. Thanks for making this job suck a lot less.

    Get it before you grow old

    It works so much better than my previous grease guns, it’s one of those things that I wish I’d bought years ago. You don’t need three hands, it stays clean, the action is good.

    Great grease gun to pair with the XL coupler

    Amazing grease gun. Easy to prime and get the air out. I purchased mine with the XL Grease coupler and have no regrets. Easy to prime and no mess. The coupler is simple to use and pairs well with the LockNLube adaptors.

    Quick, clean, easy

    I watched a couple of videos on the LockNLube website on how to assemble and fill my new grease gun. I used two tubes of bearing grease lubricating the E-Z Lube hubs on my RV. From the moment I opened the LockNLube box to finishing, it took my son and me about a hour to complete all four wheels. All the waste went into a small box lined with a trash bag. No mess on me or the gun.
