IMS Nanotech 3/8" Open Double Portafilter Spout
3/8" female threads on to the bottom of the portafilter body. This spout is treated with a non-stick coating made of nanoquartz. This coating is food safe and resistant against most chemicals. It eliminates any metal taste, increases resistance to corrosion and provide a perfect non-stick surface. The result is a cleaner cup and of course the portafilter is much easier to clean.
