  • LockNLube® Grease Coupler Locks on, stays on, doesn't leak.
  • Loop & Lock storage feature keeps you clean.
  • 20" Heavy Duty Hose and in-line hose swivel.
  • Rubber grip and ergonomic handle
  • LockNLube Rebuild Kit. Easily replace the seal and jaws, not the coupler.

The LNL153 is a high-quality grease gun that gets the job done with no leaks and no mess. We include a high-quality 20" hose, in-line hose swivel, and LockNLube® Grease Coupler. We guarantee that the coupler will lock on and not leak. When you're done greasing, just push down the thumb lever to release. 

Our Loop & Lock storage feature allows you to secure the coupler when not in use. This means no more greasy mess on your clothes, truck, and shop from hoses flying around when you pick up the grease gun. It also creates a loop in the hose easily used for storage or carrying. 

The rubber grip and shaped handle make this grease gun comfortable in the hand. Rated to 5,000 PSI, this gun puts out plenty of pressure to handle sticky fittings. We include a bulk loader port, and air bleeder valve so you can load and prime the gun easily, even with bulk grease. 

Choose Your Coupler Size



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 you 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® pistol-grip grease gun delivers up to 5,000 PSI. 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.

Pistol grip grease gun

Well made. Easy to assemble. No leaks. The lock fitting worked great. The zerk fitting To attach hose to when finished works great for storage

High Quality

Great overall experience! Bought items to get all 3 of my grease guns converted to swivel lock n lubes. Much easier to manipulate and get the grease into the fittings without the head popping off. Definitely a necessity under the truck. Thanks locknlube!!

Great product!

I was tired of my old grease guns always slipping off of the zerks or not fitting properly and allowing grease to squirt out the side. This LockNLube grease gun eliminated all of that. It "snaps" onto the zerk, making a tight fit that gets the grease inside the fitting, not all over the outside of it. I use it all the time on my mowing equipment, trucks and other farm equipment. I will never use another type of grease gun again!
