Water/Steam Tap Joint Conical Spring ØHEX 20.4×16.8mm – Ø INN 15.7×12.4mm – 6.4mm

This conical spring fits inside water and steam tap assemblies on Grimac and Nuova Simonelli espresso machines. Over time, these springs lose tension from repeated valve cycling, leading to dripping taps or inconsistent flow control. Replacing the spring restores proper valve seating and smooth lever action.

Made in Italy, this spring suits Nuova Simonelli Mac Cup, Mac2000, Optima, Premier, Premier Maxi, and Program Vip machines.
