Were all five types of beer line vinyl, or were any of them actual FDA (or it's AU counterpart) approved beverage line? The Tygon stuff I bought is lined and completely inert - the beer doesn't change after sitting in the line for an extended period of time. I have some cheap tubing that I use for blowoff and whatnot, and it goes from clear to opaque if it sits in StarSan too long (ie, one day). I've left the Tygon lines full of StarSan for a week and it doesn't discolor at all.

That's why I suggested better lines. It may very well be the chemical makeup of the beer, but it's easier (and healthier, imo) to change the lines to something inert, rather than trying completely redo your beer.

Just an update on my situation. I found a very badly pitted poppet on the keg. Also some corrosion on the inside of the post itself! Think this is my real problem. Wonder if this is what some other people are experiencing when it seems like very severe line tainting and only occurs on first pour?

i ordered 100' of the 1/4" bev-seal tubing from better bottle but it is just _slightly_ too large for the shanks i have. (stainless elbows 4329AS-3E from micromatic)

any suggestions ?

Has anyone tried this PET tubing from McMaster yet? Any objections to me ordering a 25 foot section of this to try?

Here is the part number on mcmaster.com, for some reason their website doesn't link directly very well.

Part # 5384K691

How about Tygon formulated PVC such as this?

I tried the Mcmaster part 5384K691 but it was too small to fit the shank. I returned it and then ordered the bev-seal tubing as described above.

Still looking for a solution.....

Not an ideal solution for beer line. That stuff is pretty stiff and they do warn you that it will crack with continued flexing. I have some similar tubing I bought for another project and would not consider using it for my keezer set up.

I would really like to stay with a 3/16" solution to keep the hose clutter to a minimum in my keezer but if I have to go with 1/4" it's not that big of a deal I suppose. Did you order your tubing directly from Better Bottle? Do you know if they would sell it in a 50' section?

Actually if you're looking to get rid of that tubing I would probably take it off your hands as long as it would crimp down fine on a barbed ball lock. I have 1/4" SS tail pieces on my shanks so it shouldn't be an issue on that end.
