I *think* it's M14x1.  Don't tighten the new one too much or you may
jack the end off it.  If you're in the mood for a cheap alternative,
a thickish pad of "heavy duty" Reynolds Wrap (aluminum foil) formed
up tight around the nipple and secured with a hose clamp will last a
long time and never have trouble with the threads getting bound up.

YOurs,
