> I thought only the fittings would have lead, but it's the hose material
It can be either, depending on context. (Being pedantic here just so nobody comes away thinking it can only be one or the other.)
The guy who pointed it out to me was making a sales pitch for an RV, so the hose he was upselling was for potable water-- the fitting for it on the RV was presumably selected for potability as well. Connecting a white hose to the spigot on your house could mean you're passing dirty water through a safe hose.
To be real anal, with aquaculture you have to screen fittings for other metals too. Exposure to brass will kill pretty much everything in a saltwater tank.
