Sorry, can't help you. But you might be able to take an impression of the t=
hread with some clay or duct seal and bring it to a pluming shop. They may =
be able to come up with something for you. Also, die sets come with a threa=
d matching tool. If you don't have a die set try a machine shop. I'm guessi=
ng that it's metric.
