Forces Light Oil into a Grease Joint, Flushing Out Old Hardened Grease and Allowing New Grease to be Pushed Through.

The reason why the grease does not go into the fitting is not because of the fitting; it’s because the grease has dried up inside of the joint or pin groove. Simply put, you cannot push new, soft grease into a joint if the old grease has become hard and dried, blocking the new grease.
The Grease Joint Rejuvenator® cleans the joint by forcing any light oil in through the fitting. Just fill the Grease Joint Rejuvenator® with light oil, connect to the fitting and gently tap over and over again until the new oil has completely traveled through the old, hardened grease. Like magic, all of a sudden you feel the joint open and the joint or pin can now be greased.


Features and Benefits:

  • Instantly opens clogged grease joints
  • Cleans ways and stays in milling machines and lathes

    Great invention! Excellent for cattle pens and any size machinery that has sticky fittings! Very durable.

  2. BradD

    Works! Does exactly as advertised….a rarity in this day and age.

  3. M. Pfeiffer

    Love this tool! Such an easy way to inject oil into grease fittings to help break down dried grease. I definitely would purchase again.

  4. Amazon Customer

    The larger unit in the set was not brass in appearance like in the image Works as described. Just received and first time user. Follow the directions for purging air, etc. I used Kroil as the medium, purged air, installed on grease fitting and with a few taps of a hammer, the fitting started accepting the medium. The larger unit in the set was not brass in appearance like in the image, rather silver in appearance like the smaller unit. Happy customer.

    Five Stars Kick ass!!!!!!

  8. Nick

    Strong and works! Used this on a few of my stubborn fittings on my stump grinder. After a few tries it cleared them up and I can now grease them properly! Case makes it nice to store everything together in the toolbox. Definitely built to last!

  9. Robert Littleton

    Great product. Needed this years ago. Great product.

    A well made heavy duty tool with AWESOME manufacturer customer service!! I am a mobile heavy equipment mechanic. I have a few customers that don’t know what a grease gun is or they run into a problem with a grease fitting and they just say screw it and it doesn’t get grease until I come along. My remedy for freeing up clogged up grease fittings used to be to pull out the porta power and stuff the hydraulic oil to it. That process was kind of a pain due to the bulky size of dealing with the porta power. I had always meant to order one of these sets to try. I’ve had this since February. Used it quite a bit. I wore out 1 grease coupler and the company sent me a new set of couplers because I couldn’t find them on their website. Very nicely built quality product. Very heavy duty and well made (I’ve beaten on these ALOT with a 5lb hammer) and they have stood up to my abuse. Worn out 1 grease coupler and a few o rings on the piston part. Nothing has bent or broken. Customer service with the manufacturer is AWESOME. Oh so nice to free up clogged fittings.

    had a zerk that was impossible to grease. I … had a zerk that was impossible to grease. I ordered this. High Quality tool. I hammered with a 5 pound hammer. Had to get liquid PB blaster to put in it then it finally went in. As much as I hammered on this thing it should have ruined it, but it stood up. In the process I broke a coupler and I called the company and no problem they are sending me a new one. Now I am going to work on some really old farm equipment.

    Time saver This thing works amazing. I use wd40 in the cylinder but you can use penetrating oil or any light oil. Works on 95% of the clogged grease fittings I work on. Don’t hit really hard but hit often.


    Works good Works pretty good. You may have to use it twice on more stubborn grease fittings but it definitely works for my needs. It will spray oil out of the joint your trying to unglog but it’s supposed to. Definitely wear safety glasses as it says to do in the instructions.

    Made in the usa Very good quality tools

    thanks thanks

  16. Leroy Byler

    well made Love this, well made.

  17. Chris

    Buy it This is a great tool. It is not a miracle worker. It has worked pretty well on heavy equipment for me. Only time it didn’t was due to the equipment joints freezing up. Like I said not a miracle worker. In my opinion don’t let the others make you not buy this. It’s well worth it.

  18. Lt. Jim Flip Ret.

    A nice tool to have on hand. Used this to open up some clogged Grease Zirks on my CAT backhoe. Worked perfectly and as described.

  19. JW

    Should have bought this sooner. Works great. Filled it full of WD40. After a few taps with a hammer it freed up and continued to empty the wholething in one grease zurk. Fitting works great now. Highly recommend this.
