Gator socket?
Socket with steel pins inside, one size fits all?

Hammer on a 11/16 AF socket.

If it is really badly rounded the gator may not work however 11/16 AF is slightly smaller than 18mm and a regular AF size and Brass is soft metal.

Wacking on the next size or two down in imperial works for me if not something for the job... okay on steel not sure about brass especially of the nut depth is small...

18mm is a really unusual size. Sure its not 17? Without a pic its difficult to say, but often these things have removable collar so you can get at the cartridge which needs to be removed first.
