Hmm they dont mention if the Spiedels are made out of PET plastic.  Thats a concern

They are made out of HDPE.  Don't ask me what that means though.

I use buckets myself but I see a lot of folks bemoaning the sucking airlock. I just wanted to point out that if you use the 1 piece airlocks (S shaped ones) this is not a concern as it will just bubble backwards.

If all it is is sanitizer in your airlock, I don't see the big deal. I'd rather have sanitizer sucked back than air.

well you get the air either way. just with the three piece you get the sanitizer and then the air.

It means that it'll let gas through.  If you need a good degree of gas/oxygen impermeability then PET is the way to go.


As far as the airlock sucking when you lift a plastic carboy, I deal with that by just replacing the drilled stopper with a solid one before picking it up.

I like your idea of the solid bung stopper to pick it up but, for ease I promise a 6 gallon better bottle fits great in a milk crate and serves the same purpose of preventing suck back...... there should be a poll how many better bottle user use the milk crate method I bet the percentage would be pretty high.

Yeah i saw that too, after reading about plastics online HDPE isnt necessarily food safe, it depends on the type of release agent they use

Since it's being sold specifically for food production, I imagine it's a pretty safe bet that it's food-safe.
