Flair Espresso
Flair's lineup splits cleanly on plastic. The Flair 58 family has an all-stainless brew path (cylinder, valve, plunger, portafilter) sealed with silicone - Flair's own support docs confirm no plastic contacts the brew water. The cheaper Classic and Signature ship with a plastic brewing chamber that hot water sits in, which is exactly why Flair sells a separate stainless "Brew System" upgrade advertised as no plastic contact from kettle to cup.
So with Flair, the model matters: the 58 is plastic-free in the water path out of the box; the Classic/Signature need the stainless upgrade to get there.
How clear are their specs?
Flair publishes support articles specifically documenting which models have an all-stainless brew path and where plastic contacts brew water, including the plastic pressure-gauge stem on the PRO2 brew head.
