2x 4" PVC caps
2x 1/2" ball valves (SxS?)
2x 1/2" unions (SxS?)
8x 1/2" 90 elbows (SxS?)
2x 1/2" 45 elbosw (SxS?)
4x 1/2" couplings (SxS?)
1x 1/2" male x slip adaptor
1x 3/4" female x slip adaptor
1/2" tap?

Please correct the above information accordingly.
Also what size tubing and material is the refrigerant tubing made of? (This will also help with the gland nut size)
What approximate dimensions is the tubing after being bent to that shape?
How long of tubing did you initially have to buy before bending it?

Oh, yeah. The tubing was 10 feet long before I bent it up. I had an extra 3 feet that I cut off after bending. I would assume that I used 7 feet then.

The tap is a 1/2" NPT (National pipe thread) tap. I can't remember where I got it from.

While I'm posting. I should let everyone know that Friday is the next planned build day. We should be able to get it mostly done and maybe get a frosty coil pic before I close the barrel up. I'll try to remember to do that. Everyone seems to love those pics.

Any other requests for lots of pics of a specific part of the project?

I'm working on a design for a chiller that is self contained. Should make it easier if someone wants one shipped to them. I've got most of the major parts for it. Just need to get a few other things and build it, I guess...

Anyone want to try one out for cost of materials?
