High quality and fixed the drain fitting leak on my gas water heater. So I went to replace the small angled drain valve on the hot water heater with a new ball valve so I could do annual cleanout maintenance. Well what seemed like a quick swap turned into a multi-day ordeal. The new 3/4" ball valve didn't seem to thread in far enough and despite teflon tape and a giant pipe wrench and my super-human strength (yeah right) the new valve would not stop leaking. After draining the tank again I was able to sumise that the factory had done a lousy job of threading the tank fitting and misthreaded the original and my first replacement. After re-threading and further threading the second replacement valve didn't shed a drip - bone dry, finally!

Excelent tool

Product was as advertised.

Exactly what I needed. I didn't have to tap new threads, but this worked great to chase some worn well adapter threads so I could install new fittings.

Good metal. Didnt deform or lose sharpness even when tapping stainless steel

Used them a few times and they have worked well.
