Silicone replacement group gasket for E61 group head espresso machines. Silicone gaskets are known to last much longer before needing to be replaced as well as not recreating the odor that rubber gaskets can produce over time. The 8.5mm gasket is thicker than the 8mm gasket, meaning it will create a seal sooner while tightening the portafilter into place.
