Grease Joint Rejuvenator® Professional Model - Patented - for Flushing Out Hardened Grease from Shafts, Bushings, Joints and More! (#7862)

WOW!!!! Took a chance. Tired of replacing zerks. This thing blows them out fast! Even on an excavator where hands dont or wont look for a grease zerk and they go unused for a couple weeks, this thing blows them clear quick. I use hydraulic oil mostly. Solid stainless construction. Comes with short whip for hard to reach places and packaging is strong and reuseable. A solid 10 / 10!

Worked perfectly, hardened grease in a captured pin at a difficult location, only other option was a tear down. Filled and used it twice, completely freed up the grease and regreased it works great.

I bought this tool to free up some plugged up grease fittings on my backhoe and at first it didn't work because I was using PB Blaster and WD40 and the plunger was bouncing back after hitting it. The key to make this tool work is to fill it with ATF fluid/transmission fluid and to use heat if you can on the joint/fitting. It freeded up some old grease on my old backhoe and saved me a lot of money in repairs.

60% of the time, it works every time!

As designed works great!

Works good

Works well

I purchased this tool with the expectation that it would fit the 1/4 in-28 SAE-LT grease fitting. The 1/4 in-28 SAE-LT is the most common fitting used in the US. To get the head to work I had to unscrew it completely to get it to disengage from the fitting. If you do this be careful to not drop the spring and splines onto the floor. Besides that it worked great. I can always get a larger head for the tool so is an easy fix.
