As can be seen in the picture, my garden hose reel intake valve is a steel pipe 3/4" in diameter inside the hole. As I haven't worked with this kind (thinner wall) of steel pipe (only indoor galvanized, which is thicker), I wanted to ask which size of hammer flaring tool I should get to flare another terminal. This one has served about 4 years and it is bust as the flared part wore off and the nut and gasket that were on it (not pictured) slid off. I plan to shorted the pipe to just above the current flaring and the reflare it after I get a nut and gasket replacement.
So basically, if the inside of the steel pipe is 3/4", do I just get a 3/4" hammer flaring tool or is it different for this kind of pipe?
