I wish I had known about this handy dandy little tool many years ago. It made an otherwise impossible job doable. Even for an old man with arthritic hands. I couldn't recommend this tool anymore that I already am. Well worth the money. I'm actually looking forward to using it on four more valves that I am going to be replacing.
Finally, a sleeve puller that actually fits over the copper supply line easily to be able to thread on the nut. Worked flawlessly!
This tool worked "perfectly" and as advertised. Without it, I would have never completed as easily as I did my plumbing project. Thanks to those who created and engineered this awesome tool!
