La Marzocco Removable Portafilter Spout O-Ring - Smaller
$2.00
There are now two sizes of spouts due to a revision in the cut at the bottom of the portafilter. Some work best with the small o-ring, and others with the large. This one measures 3.53mm thick with an outside diameter of 14.5 and an I.D. of 8mm.
