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?

  • There may be different joints in use. Do you have a service or repair manual? Do you have a picture? – mart Feb 03 '15 at 12:15

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).
