Hmmm, further research turned up a Canadian Conservation article that the Tygon B-44-3 is still vinyl tubing. From that article it sounds like Tygon SE-200 is FEP lined, much the same as Bev Seal. Looks like USPlastics has it "on order" in 3/16" ID.
Wow that's over $100 for 50 feet. I got 80 ft of 1/4" ID Bev-Seal tubing for $36 from Better Bottle. I know it is meant for the application, PET lined, can deal with the pressure. For a balanced system I'll just use the little epoxy mixers to reduce pressure in the lines. They are HDPE plastic, just like our fermenting buckets so I don't have any issues with beer contact.
