Where can I find bendable stainless tubing online or in a store? I am looking for something in the range of 3/8 1/4 or maybe 5/16 that I can bend into a coil to use as a temp controler for my fermenter. Copper would impart off flavors if left submerged during fermentation. I believe stainless would be fine but can't locate any at local hardware stores.

My first suggestion would be www.mcmaster.com.

So are you going to recirc ice water or glycol through that or something? interesting. Never heard of an IC serving that purpose.

mind If I ask what kind of fermenter you're talking about and why not use a jacket on the outside walls?

Buy a pre-made stainless chiller from a place like www.midwestsupplies.com
The word bendable and stainless don't go together. Believe me, I just tried it and ordered one already done.

ask a hot rodder. www.jegs.com sold as brake line. and as said above it is very tough to bend. Maybe the car guys can give tips on forming it nicely too, some do all their lines in stainless.

I have a cheap homemade system using a tub of H2O that I control with an aquarium heater and currently DO use it to heat a jacket around my Mini-Brew conical fermenter. (Jacket is here http://www.homebrewtalk.com/f51/home...onical-156874/ ) But I think I can get better control with an internal coil that I can pump the same controlled H2O through. To compare, when I chill my wort with simple copper wort chiller it will chill much faster than if I simply set it in a jacket(sink) of ice water. So I would like to try the same concept with fermentation. I believe it is easier to conduct hot/cold through metal then plastic, and this conical is very thick.

I have a friend that own an HVAC company. I work with him now and then. I helped him install the chillers at a commercial winery here. They used the same concept to control their wine fermentation temps. I looked like an IM chiller that was stainless. I came through the fermenter lid and was held in place with compression fittings.

A better selection of tubing.

And everything else for the DIYer too.

speedymetals.com has 1/4 " tubing as then as .035 thickness. they don't have a min. order. you mite get a few inches and see what you can do to bend it.

Exactly what I want to do (if not cost prohibitive) I would cut 2 holes in the top of my fermenter for bung plugs with holes for the tubing to slide through. Probably too expensive but never hurts to check into it.
