Can anybody tell me the NPT port size of this solenoid? I don't know if I'm slow or what but I can't find the NPT port size. If the Link doesn't work for some reason it is the $83 double solenoid on andymark part number: am-2343

It is M5 port which is a metric thread. Q&A has said this is a metric equivalent to 1/8NPT.
