The Original, Made in The USA by LockNLube! Cleans and flushes Out Old Dried Grease from Fittings, pins, shafts, bushings, and Joints. Uses penetrating Fluid and Hydraulic Pressure.

Have used these for years just needed a new one. Beats the hell out of taking the zerk off and trying to put a new one on. They hold up to abuse well and work great.

I am NOT a skilled mechanic. I am 71 years old and what little I know about mechanics I figured out on my own or got help from buddies (in the old days) or found a solution on Google or You Tube (now a days).This was my problem: I recently bought a Texas Pride 16,000 GVWR 22' + 2' lowboy trailer with tandem axles and drive over fenders. It was time to add a little grease to 6 fittings. Everything went well on the first 5 fittings. I could not pump any grease into the last fitting (of course).I have been tinkering with stuff for a long time and I know how to use a grease gun. But I have never had a fitting to not accept grease. I removed the fitting (remember this is a brand new trailer) and cleaned it up. The fitting was deformed. That made me wonder if this spot had been greased at the factory. (Turns out it had not.). Anyway, simple fix. Off to the auto parts store to purchase my zerks.Got home, installed a new fitting and NOTHING. So I removed the fitting and put in another new one. Still nothing. I put a fitting on the grease gun and it took grease (as long as the fitting wasn't screwed into the trailer. So grease was definitely able to pass from the grease gun through the zerk.Time to check out You Tube. I found a video about the Original Grease Buster. I read reviews, compare it to knock-offs and thought this thing couldn't possible work in my situation.Well, I didn't have anything to lose thanks to Amazon's free returns. I received the Original Grease Buster the next day. I followed the instructions in the video and on the packaging. Less than 15 minutes after I received the Original Grease Buster the axle hanger was fully greased and the trailer was ready for the road.Final thoughts If you work on anything that has grease fittings you need to buy an Original Grease Buster and drop it in your toolbox now because it might not take you 71 years to run up against a fitting that won't take the grease. I know the dang thing is pricey. But IT WORKS.

Had mixed results based on different circumstances. If your grease joints are seized solid this won’t perform a miracle but if it’s just gummed up this will work just fine. Build quality is very nice. Great tool to have on hand. If I had this before the one bad joint it didn’t work on would have been addressed years ago and been fine. This will keep you ahead of the game

All in all this thing works pretty good, it's kinda messy to store i wish they include a better bag to store this oily thing. Also yall need to make and adapter to go to sds hammer drills. The air hammer is nice but no one makes a cordless air hammer. I ended up making my own. Sds is the way to go.

Every one who has heavy equipment needs one!

First one came missing parts. Happens returned in exchange for a new one. New one showed up fine. Went to use it, 3rd fitting in it stopped sealing. Just push’s fluid out the end past the fitting . Thought maybe my fitting was bad, replaced it. Same thing. Leaked on every fitting going forward including the ones it’s worked on.

Worked great . would recommend getting one.

Great tool to free up grease fittings. Easy to use and fill with favorite penetrating oil. Very solidly built. Price is a little high though.
