Copper refrigerant tubing for chillers

[andy6026]

The old immersion chiller I made was destroyed by winter, so today I made a new one using 50 feet of 1/2" copper refrigerant tubing.

A question came up about this tubing: does it contain any lead? While obviously copper drinking lines do not, I can't seem to find any information on this tubing that is typically used for refrigerants which may not require the same standards.

Can anyone either set my mind at ease or warn me that I need to start again? Thanks!

If it came from China I wouldn't use it. Then again I have no use for anything out of China.

It is made in Canada.

Regardless of country of manufacture, the ASTM standard for any copper tubing sold in the US is less than 0.05% lead. That includes refrigerant tubing. You should be fine.

Thank you very much. That's very helpful.

Thank you for asking this. I recently made a 50' chiller from that material. I just used it and was wondering if I screwed up my beer.
