A lot of brass fittings and fixtures with lead in them. Makes it easier to machine.

I wouldn’t be surprised if a lot of no-name Amazon and aliexpress plumbing fixtures still have a lot of lead in them. Keeps your cutting tool/machining costs down.

Even big box stores that are careful sell a lot of high lead plumbing parts - they are just marked not for potable water and sold for use with gas pipes.

		Can still get full lead solder for similar reasons if you’re a cranky old plumber. Probably can’t get away with using it in new builds but anything else, I’m sure it got used regularly well after the 1986 “ban” and still today.
