I wonder how much Oxygen actually permeates through the tubing. Hard data would be nice.
Thanks for the info.
I have been dabbling in some of the LODO techniques on the Hot Side and have to say my Lagers have gone to a new level - now if that is LODO or just getting better at brewing I do not know. Right now my brewing space is small and does not lend itself to hard piping very well - I have to move things like the chiller, hop rocket, pumps around. I could probably do it but I thought if there was a silicone alternative that had some of the properties (high temperature and flexibility) that would be easiest.
I use silicon tubing for whirlpools of 15 min at 165 degrees, my DO Meter still reads < 1ppm before pitching and oxygenation
I do treat all of my mash and sparge watter with 20mm sulfites though.
I also don't recirculate my mash and do a single infusion for 60 min
I'd recommend first getting a DO meter to test your process and see if there is even an issue that's worth remedying. Good chance your current process with the silicon tubing is OK! I know the DO meter is a little pricey at $230, but its really the only way to truly know if your hot side process it working.
I use this one and take readings at mash in, pre-boil (after lauter), and post boil. I always have hit < 1ppm.

I also use 1000 20mm prolyprolene balls as a mash cap and lauter/boil cap.
