FWIW...

I just looked at the Chemical Resistance Chart for the large (>200gal) PE cone bottom tanks from US Plastic. It specifically mentions being beer resistant, as well as 100% ethanol.

It also lists butter, coffee, cola concentrates, corn oil, dextrose, milk, molasses, shortening, vanilla extract, vinegar, water, wines, and whiskey as other uses. So I guess there's no doubt that they're food-grade.

I see 2-3 of these in my near future...

Default Beware of plastic odor/taste!

I got my 15 gallon tank and have assembled a valve and drilled the hole for the airlock. When I opened it, I noticed a REALLY STRONG plastic smell. I washed it out and let it soak with oxy clean for a day, no change! I have read that a mixture of vinegar and baking soda with water and soaking for 48 hours will fix it. I will advise but I would NOT buy one of these until a fix is determined. I would have to say as-is we would be brewing a "plastic pail ale"

When I purchased my first plastic conical (30 gal) from US Plastics I did notice some off gasing from the plastic. I left the tank outside for a few days and then soaked it in Starsan for a week. After the Starsan there was no "plastic smell" off gas at all. Since then I've had not problems at all with the conical.

If there was one problem with the 30gal version it's that it's too big to fit in my temp controlled fridge. Jan/Feb/March lagers are fine but after that it's fire and forget ales.

So I got a tube of food grade lube and put a large bead around the top of the conical tank and screwed the lid down into it. So there's a slick mess around the rim, but none of it gets into the tank, and effectively seals the lid shut, so the airlock bubbles and nothing gets in. Hope that helps!
This works great! Second batch is bubbling away nicely. Thanks for the great tip!

Has anyone done anything to the inside of these at the outlet port? Mine has the huge plastic nut on the inside that creates a pretty big lip for the yeast to settle into, I was thinking of filling it with food grade sealant?

I reposted my blog post on the valves and use of the cones at www.hessbrewing.blogspot.com. Look for the post, Conicalus for the Restivus.

Are you talking about the bottom port, or side port? If you bought the right version (FD - full draining, see my write up) there is no huge plastic nut at the bottom. If you are talking about the sideport, the round washer that holds the port in place (p/n is in the write up), there is no issues with build up and any sealant is overkill and unnecessary.

We have been using the cones for almost a year and have put over 75 batches through the conicals with ZERO contamination issues (or any other issues for that matter).

Mine looks like this, just like the one at the beginning of the thread. Yeah I am talking about the dump port. Looks like I didn't get the best option (sigh). Any ideas to improve what I have? It's an Ace 15 gallon.
