Default Immersion Chiller Tubing ??????????

Going to make a immersion chiller. I been looking around for copper tubing and i found alot they where to types Refrigeration Tubing,General-Purpose tube can i use both or is there a right or wrong one to use.

I found 3/8-Inch Copper Refrigeration Tubing 50ft for 39 buck seems like a good deal. I wanted to get 100 ft make one immersion chiller to put in the work the make a short wide one so i can put in the sink with ice water . So the water would come out the faucet flow thought the first chiller that is in the sink with ice water then to the chiller in the wort. I want to do it this way so i can cool my wort to 60 as fast as i can .

What do u guys think.

The refrigeration tubing is fine if you don't plan on having to solder any elbows or other fittings on. I think the refrigeration is slightly smaller O/D than the "type L" tubing which is slightly more expensive.

The "type L" copper tubing is what you need to use if you are going to solder fittings.

I am speaking from experience using half inch but am assuming 3/8 is no different with respect to the different grades of tubing.

i used the refigeration tubing. dont remember the exact length that i coiled as it was quite a while ago but i think i bought around 35 ft. (5 gallon batch). i just used hose clamps to fit a garden hose fitting on it and then added a length of hose to drain into my lawn. knocks it out in about 10-15 minutes assuming the water is pretty cold, which it usually is as i live in CO. been using it for 5 years now with no problem.

Not really. There are two differences between plumbing tubing/pipe and ACR tubing/pipe. The biggest one is that plumbing tubing is labled by it's nominal size, and ACR by it's actual OD size. For example, 1/2" pipe for plumbing (be it type K, L or M0 is actually 5/8" OD, but it you buy 1/2" ACR, it's 1/2" OD. 3/4" K, L or M is 7/8" OD, 3/4" ACR is 3/4" OD. Plumbing tubing and pipe also vary in wall thickness, which is what is designated by the K, L or M type, with K being thinnest and M thickest, and the price goes up significantly with the thicker walls. BTW, there is absolutely nothing wrong with using the cheaper type K for an IC, and it's actually prefered for maknig a slotted manifold.

As to soldering, any of them can of course be soldered - indeed, the vast majority of all HVAC connections using ACR tubing/pipe are either soldered or brazed.

Do you think Petra 3/8-Inch Copper Refrigeration Tubing would work good for a chiller . Or do i need 1/2in

Mine is 3/8" but I wanted to extend the height so it would clear the top of my keg. Picked up some 3/8" refrig line and 1/4" connecters fit. A little solder and its water-tight.

I'm no plumbing whiz lol. I forgot there were 3 types (K, L, & M). I just remembered that I tried sticking a 1/2" 90 on what they called "refrigeration" tubing at Lowes and it didn't fit. The 90 was too big. I think I got type "L" cuz thats all they had in coils. K would be cheaper and maybe even easier to work with.

+1 on what you said about the thinner stuff being better for manifolds.
