LockNLube Easy-Prime Lever Grease Gun
SKU: LNL251
Easy-priming, high pressure, and European engineered, the LockNLube Easy-Prime Lever Grease Gun will change your idea of what a grease gun can be. The lightweight design does away with the follower rod and plate, replacing them with a simple, reusable cap. The plastic follower is pulled up as you grease and scrapes the tube clean—no drips, no mess! The precision design allows for fast and easy priming, enabled by a vacuum seal that keeps the follower sealed tightly. Our LockNLube® Grease Coupler, In-Line Hose Swivel, and 20" whip hose mean no leaks, no mess, and no hands needed to keep the coupler in place.
The lever-action allows for high-pressure applications with less effort and shorter strokes. Designed for use in harsh conditions, with sturdy construction and seals that keep dirt out. The LockNLube® Easy-Prime Grease Gun will provide years of easy service on your farm, job site, or in your backyard garden.
Includes 10 reusable followers.

The new LockNLube Easy-Prime Grease Gun works without the need for any spring mechanism. Simply insert the cartridge, insert the follower plate, and get started. The vacuum in the grease gun head moves the piston smoothly upwards all by itself. The variable stroke ensures the grease gun can be easily operated with minimal lever movement.

the best grease gun ever
This gun is awesome I wish I found this gun years ago.

Grease gun
Have not used the gun yet but think the coupler I previously purchased is great. However I received an email this morning advertising a cap to cover the open end of the gun, for the price I think this should have been included with the gun kit


Simply amazing
After decades of messy cartridge changes greasy hands are a thing of the past with zero priming issues. Well worth the money.

love it
I usually made a mess with grease guns due to the connector falling off a fitting, or when replacing grease cartridges and getting the gun primed. This gun solves both problems.
