The best sanitation hose is probably Sealand's ODORsafe hose, but it is pretty expensive and fairly stiff and hard to work with as a result. It is far more resistant to odor permeation than other hose.
The research I just did into this suggests that Trident 101 is better. I'll see if I can find where I read that. Back in a few . . .
Edit: Of course now I can't find it. This link says, I think, that OdorSafe is better. It also says that there's a much cheaper equivalent. Re: Ping Peggy re: sanitation hoses
