Milwaukee unit works on Rigid with minor modifications.
I bought the model for the Milwaukee M18 gun. I have a ridgid grease gun. The only modifications for it to work were to loose the Oring on the return port. Add a copper washer to the banjo bolt that screws into the original port for the hose.

Works as advertised
This is a great addition for a battery powered grease gun. The fit was a bit off for my Milwaukee gun so I had to slightly drill out the bolt holes to get it to fit, not sure if it was a Milwaukee or a lock and lube problem, either way I fixed it and it works fine.

Worked but failed later
Had this for a Milwaukee grease gun and worked fine until grease started to bypass the ball valve and return to grease gun. The tool would no longer build pressure. I cleaned and took apart pressure release and test with air pressure and found air was escaping past the ball. I don't believe this is repairable seeing how the drilled ports where the ball sits is the issue. This might've been a mess up by the manufacturer but now I'm out 60$.

Worked great, just didn’t fit into my setup
I’m a heavy truck and heavy equipment mechanic, so we have power greasers in the shop. I have added a grease fitting into both of my Milwaukee gun tube heads and fill them from the power greasers that way. I added this attachment on and realized I had to give up the threads where I had the refill fitting to be able to fit this attachment. I did use it for a bit just to see how the valve worked and it worked awesome, I wish I could have kept it on. Tried to come up with some rigged up way with fittings to make it work but it was just easier to take it off and continue without it. If you don’t refill your Milwaukee grease gun with a power greaser and do a lot of hard greaseable areas then buy this, it does its job and saves your tips and o rings if you have the lock and lube brand tips or something similar.
