My skinner valve has a 1/2" female socket that requires the male member (?) to have have 2 holes in it for the 2 male pins that are inside the female 1/2" socket. Still with me?
Yes, but you will have an easier time finding it if you use the standard terminology. The side with the pins is called the male end, and the side with the holes is the female end. It does not matter that there is an outer case on the male end that encloses the female end.
So I need the male member to insert into the female socket, is this a common plug?
It's probably a "Cannon" plug, but how 'bout you post a photo or two, maybe we can identify it.
I looked around the transits and the prevost and they all had a bisexual male plug ( i.e. 1 hole , 1 pin).
That's actually called "hermaphroditic."
... If you understood this post then a picture in this case was worth, aprox 85 words.
I think a photo is worth more than that; if you can post one it would help.
