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

James W.

"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."

Kyle H.

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

Clean and Tidy

Keeps the hose tip clean and tidy and prevents latent grease from being flung around. Also prevents dirt from getting into tip that could get transferred into zerk. If you choose correctly, you can also color code for which grease you have in the gun.

This cap won’t let you down

The cap works well keeping out dirt and grime from contaminating the grease.
