Replaceable stainless-steel pad/pill for foam production in the ST-73.1 foam lance.
Please note: The ST-73 comes with two different foaming mechanisms—this stainless-steel pad (pill) and also a mesh gauze. The pad is replaceable while the mesh can be rinsed and reused and is ideal for hard water environments.
ST-73.1 uses the stainless-steel pad.
ST-73.2 uses the plastic mesh.
See the video below for instructions on replacing the pad.
