GREAT COFFEE JUST GOT EASIER
Requiring half the force to produce the same pressure as its predecessor, ROK's all-new and totally re-engineered Glass Composite (GC) brew chamber & piston make it easier than ever to handcraft rich, crema-topped espresso.
Easily retrofitted to your existing ROK/Presso Espresso Maker—since we know you still love it—the GC Conversion kit provides enhanced insulation, pressure, accuracy, and uncompromising performance.
New glass composite brew chamber design provides superior insulation and produces same pressure as original with significantly less force, delivering twice the performance.
Smaller holes and locked-in placement of the overhauled silicone shower screen provide greater precision for a cleaner and more consistent extraction.
Compatible with all previous ROK/Presso Espresso Makers.
4-piece kit includes glass composite brew cylinder & piston/plunger, silicone o-ring and fitted silicone dispersion screen.
Designed and Engineered in London
Made in China
