Counterflow Chiller question

[Bigpete9000]

Looking for some help... I am building a counter flow chiller. instead of the normal 3/8 copper mine is 1/2" id copper to match all the other 1/2" connections i have. The outer PVC hose is 3/4". I have a 3/4" tee's to connect the hose to and a 3/4" to 1/2" reducer for the copper. Ok now here is the question i want to connect my 1/2" camlock but i dont know what i need to connect to it .... here is picture.... any suggestions would be very helpful..

Can you push more of the copper out of the end of the tee? Screw the 3/4 npt onto the tee and solder the copper through the other end so it sticks out a few inches. Then solder a 1/2" connection for the qd.

You'll need a 3/4" NPT x 1/2" tubing adapter which may be hard to find.

Alternatively, a 3/4" x 1/2" NPT bushing and a 1/2" adapter like this

Then for the camlock you'll need a female npt adapter like this

You may need to drill out the first adapter to allow the tube to go all the way through, some have a little shoulder to stop the tube from going through.

I don't think you're really using 1/2" ID copper tubing because that would be nearly 5/8" OD. I think you mean 1/2" OD copper. If it were me, I would use a 3/4 x 1/2" hex reducing bushing in the tee first, then thread the cam F into that. If I'm not mistaken, the clearance between the 1/2" OD copper and inside of the cam F are close enough to slightly flare open the copper and directly solder it to the cam F.

The long way is to go compression fitting.
