As far as I know, these are the ones that break and fall into the water. Maybe it's wrong. I use some of these fittings on a reverse osmosis drain to divert waste water into a jug that occasionally waters plants or flushes toilets. The list of plastics and o-rings does not contain enough information to use on the supplier side.
