Fun tool for antique radiators

I may never use it again to get a spud type union into my 1926 heater radiators but it worked well and it was fun to work on steam era tech!

Most Liked Negative Review

Used to remove internal fitting on hot water radiator valve

The size that fit was too small and stripped because I couldn't get enough purchase in the internal fitting, next size up was too big, so it didn't work for me. Not sure how to rate a product that I can't really use, but it is intended for this use and doesn't work. So keep that in mind if you really need that internal fitting to come out, this may not work.

Broke on first use, like others have said.

Would have been a great tool and useful for radiators but it snapped off using it on a ½" fitting. Maybe larger fittings won't snap off but I bought it specifically for this task. Bought the more expensive option thinking it would be better quality. Made in Taiwan, who are not known for quality.

Broke first use

Was just starting the job and it broke right off with very little force. Completely worthless.

Cheap metal broke on first use

I turned a 1/2" radiator valve, tightening new threads to new threads, got to the point where it felt about night enough and it broke completely through in my hands. I'm not a plumber so I doubt my hands can do anything extra strong with this product. It's just cheap pot metal.
