On espresso machines, there is some kind of pipe joint which allows the steam wand to move while maintaining its seal. What is this component called?

It is called a "steam wand gasket". Technically, it's a ball-and-socket joint made out of two concave PTFE (Teflon) gaskets and an EDPM gasket for the seal.

There may be other designs too; I learned this by watching Saeco StarBucks Barista - How to Replace Steam Wand Seals and Gasket (YouTube video).
