Rancilio Epoca C/10 "Clever" Steam Valve Knob This is the same design that replaces the older Rancilio #10-060-181 steam valve knob on Epoca C/10 machines. COMPATIBILITY Fits: Rancilio Epoca C/10 Replaces: old Rancilio #10-060-181 INSTALLATION Quick DIY swap, pulls off the valve shaft and presses the new knob on. PRO TIPS If your old knob has a set screw or pin retaining it rather than a pure press-fit, remove that first to avoid cracking the new knob during installation.
