O-ring 02025 - FKM

O-Ring OR 02025, FKM (Viton)

One of the most-used o-ring sizes in the entire espresso machine world, it turns up in steam and water valves across nearly every manufacturer, and also works well as a flat solenoid flange seal in place of the silicone F_252. This is the FKM (Viton) version for maximum heat and chemical resistance. FKM is the ASTM designation for Fluorine Kautschuk Material, originally developed under DuPont's Viton® name.

PRO TIPS

• Some of the cross-reference numbers above are for o-rings in other materials at the same dimensions, that's fine for a like-for-like size match, but if you specifically need Viton's heat/chemical resistance, confirm you're ordering this FKM version rather than assuming a listed cross-reference number guarantees the same material.
