If you’ve ever struggled with a stubborn, clogged grease fitting, you know it’s a frustrating—and usually messy—situation. The problem is, old grease can harden and gum-up inside the fitting, which means you can pump away on your grease gun all day long, yet the grease inside won’t budge.

More often than not, your new grease will ooze out everywhere too. Gross.

The folks at LockNLube have been there, done that. That’s why they invented the LockNLube Grease Buster.

Simply press the tool onto the fitting end, then whack the backside with a hammer.

Voilà—the grease inside will be cleared out and, as an added bonus, you can relieve some stress with a good ‘ole hammer swing too.

In other words, if you work on a lot of old cars, trucks, tractors, Ag or construction equipment, or industrial machines, this tool is worth its weight in gold.

As the name implies, the LockNLube folks make a ton of handy grease and lube tools, including industrial-spec grease guns and plenty of versatile grease couplers and accessories.

The Summit Racing team gives you a closer look at this innovative tool from LockNLube in the video below, and you can find all the details on the Grease Buster here.
