– Heavy-Duty Adjustable Hydraulic Coupler Grease Fitting And Bearings Cleaner - Shop size

Didn’t work on the two plug I had to change out

I had 2 zerts on my skidsteer that wouldn't take grease. I took them out and made sure the zerts were good and they were. There was dirt and rust build up in the holes in the pins. I sprayed PB Blast and a couple pumps of grease in the grease buster, put the plunger in and beat it like a Sunday morning hard on! And bam! It broke the dirt and rust free. Way easier then taking the pin apart to clean it. Well worth the $50.

Don't use brake clean blew out a rubber o ring in under 2 minutes. Tool works but could be of higher grade material.Deformation at the hammer spot within an hour. It did however allow me to grease areas that weren't taking grease even after heating up the old grease

Don’t waist your money!Used on several different clogged fittings, no help!!Also very small and hard to fill!

I’ve been mechanic since 1980. I’ve loaded light oil docent into grease guns for years. This just simplifies it. Works exactly like it should. Load up whatever is stuck and let it sit overnight, done
