A/C water valve, capillary tube connection.

['68 Charger]

Hello all,
I'm installing my A/C water valve to the firewall (1968 B Body). I need re-connect the capillary tube to the back of the water valve.

Questions:
Pic 1. What is this screw (red arrow) used for?
Pic 2. Do I bend these tabs (yellow arrows) over to secure the tube housing? If so, outwards or inwards?

thanks

You replaced the seal with the NAPA kit? The small screw sets the tiny bit of travel for the capillary system. The tabs are delicate, they bend outwards. If they don't break that is.

No I did not, wasn't aware of the NAPA kit. thanks

As for the screw, do you set it and if so what are the adjustments to look for? Because once the AC box is in place there's no getting to that screw easily.

Thanks for your reply!

Here's the seal. Also available with the seat seal from Detroit Muscle Technologies.

As for the screw - don't mess with it. It doesn't need adjustment.

Thanks!!

So just run the screw all the way to snug? And leave it be?

Also while we are on this subject how sealed is sealed if i close the valve on mine there is a slight weep of air when i blow through the valve. is this enough or does it need to be fully air tight

Sounds like a bad seal. After I rebuilt mine, it will not pass air.

Thanks i just purchased a kit and pulled my tap apart but trying to work out how the inner tube rubber goes in and which way it sits as i think mine is missing does the inner rod stay in place or do you remove it?

Usually the valve seat seal is in good shape. The NAPA seal has good instructions on disassembly. I believe Detroit Muscle Tech has the inner stem seal package with the body seal. There is apparently two different sizes, they have both.
