The fitting is a combined banjo bolt and vac takeoff for the wipers. the banjo bolt holds the vac advance pipe to the manifold and the wipers can be plugged onto the vac tube on the head of the fitting. There does appear to be some sort of diaphragm or valve but I have not dismantled one to look inside. The threas is a unf thread, I don't have one here to check the size but it could very well be 7/16 UNF.
