LockNLube Easy-Prime Lever Grease Gun


22 reviews

The Easy Priming, High Pressure, European-Engineered, LOCKNLUBE Easy-Prime Lever Grease Gun will change your idea of what a grease gun can be. Its lightweight design does away with the follower plate and rod, replacing them with a simple, reusable cap. The precision design allows for fast and easy priming every time enabled by a high-pressure vacuum that keeps the follower sealed tightly from the bottom. Our LockNLube® 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.

Features & Benefits:

  • Easy priming: Unique plastic follower and vacuum suction means easy priming every time
  • High pressure: 10,000 PSI max. Pressure remains constant up to 40,000 priming cycles
  • Lightweight: No follower plate or follower rod needed makes the gun lighter and more compact than anything on the market 
  • No leaks: Reusable plastic follower means no dripping grease. LockNLube coupler means no leaks from the top.
  • Storage: Features Loop & Lock storage design

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.

Buy this Easy-Prime Grease Gun

Used my Easy-Prime grease gun with the Lock'NLube tip for the first time yesterday. Very pleased with the clean, easy set-up/prime process. And the Lock’NLube tip is equally easy to use. Swivel action of the hose makes it easy to maneuver into tight, awkward spots. One of my best purchases in a long while.

Easy load grease gun

It was easy to load and prime. The lock and lube fitting works well. I really like the fitting attaching back to the pump so it stays clean and easy to hang up.
