LockNLube Professional Pistol-Grip Grease Gun


71 reviews

An upgrade to our popular LNL152 pistol-grip grease gun. The LNL252 delivers up to 8,000 PSI. A cast aluminum head gives you the quality of a cast head, with the lighter weight of aluminum. A large-ergonomic grip means you have more grip on the grease gun. An integrated handle clip makes storage clean and easy.

Also includes our patent-pending loop & lock storage design for improved storage and carry. To reload the grease gun we use an oversized locking notch on the bottom plate (not a tab). This makes for fast and easy reloading and minimizes any risk of knocking the follower rod out of place before the barrel is reattached. As seen on TruckU on the Motortrend Channel!

Also includes:

  • LockNLube Grease coupler
  • In-line hose swivel
  • 20" hose rated to 14,000 PSI
  • Air bleeder valve
  • Replacement seal kit

Finally a grease gun that works perfectly!

Excellent product! This grease gun is THE BEST grease gun I've ever owned (and I have had 5 of them in the last 60 years)! The last brand I bought in a store a month before this one was just a piece of junk and absolutely didn't work. I turned to the internet to find something a lot better and could not be happier with this item! I highly recommend it to anyone looking for a grease gun that actually does what it is supposed to and is made well!

Excellent quality, build design and features. I had a grease cartridge loaded and air purged in seconds. For the average person, This pistol grip grease gun and the Pro Series lever grease gun are the only two grease guns you'll ever need and only have to buy once. Forget those cheaper hardware store grease guns that fail to function properly with time and use. I have a cheapo and it's an aggravating piece of garbage. Never again. I'm a Lock N Lube user for life now!

Heavy duty grease gun

Arrived quickly and well packaged. Appears to be very well made. Construction is heavy duty. Swivel grease hose is a great idea and the 4-tooth end is much better than the traditional 3-tooth ends in cheaper grease guns.
