I learned my lesson today

Dang, it's my job as a toolman to say something. That old wrench and a claw hammer are two tools you shouldn't use on a brass fitting. LOL
was gonna use the hammer to try and smack socket onto the fitting. and that wrench was gonna get bent to install the new bell style unit but I then realized it was a 9/16ths wrench. not a 1/2"
