Barista approved! 8 mm male thread, with 1.2 mm holes. Great for micro-foam and latte art, but be prepared to wait - they are not quick. Which steam wand does it fit? For Nuova Simonelli, only this one. This tip only fits the newer style version of a steam wand with a female thread to accept the tip, such as what is used on the Aurelia and Aurelia II models.
O-RING NOT INCLUDED!!
Although this was popularized by Nuova Simonelli, it is also used by other manufactures.
