hfmb;

That capillary tube connects(ed) to a sensing bulb in the heater box. When working as designed, this allowed for a thermomechanical, closed loop, automatic control of the air temp coming from the heater box.

If your valve is leaking, you can still use the "new" one as a replacement if it doesn't leak, you will just need to adjust the temp totally manually, because there wont be any closed loop function (opinions vary on how well this worked in the first place...).

Next time, try to ask before cutting.

Cheers
