Pearl;

That capillary tube was part of a "closed loop control" system ala 1960! The bulb at the end of that tube was located to sense the temp of air out of the heater system and it fed back to the valve to modulate same and keep a set temperature.

If your replacement valve works well and doesn't leak, that's great...the automatic regulating part is not as critical in my opinion...I can just adjust the control manually.

Cheers!
