LockNLube was founded by farmers and loggers with the goal to End Greasing Frustration by creating tools that work better and last longer than anything else on the market.
Our tools are built to solve the unique challenges farmers face and stand up to the heavy use and demands of farming. LockNLube tools make farm equipment maintenance faster, easier, cleaner and less frustrating. Increase uptime, save time on routine greasing and tire inflation, reduce the cost of wasted grease, and prolong the life of bearings and bushings when you know that the grease goes in, not on, the machine.
Trusted by Farmers since 2013!

“Greatest thing since the invention of the aluminum beer can ... won't own a grease gun without it.”
"I had a couple of pins on a tractor loader that I recently purchased that would not take grease. I used the grease buster on them and it worked exactly as advertised. The whole process for two fittings took 20 minutes from opening the package to grease fittings that work as they should. Great product!"
"I can’t explain how much I love this
chuck. I have been using different
gauges for years but this beats them
all. I would recommend this to
anyone who asks me.
I am so happy that I found this."
