Breville Sage OEM Group Shower Head Water Dispenser SP0020016 Barista Express

Don't buy this one! I'm certain I'm using this on the correct machine (Breville BES870XL). The groove where the rubber gasket sits is too deep, so the portafilter doesn't seal properly. It was an epic taking the machine apart to replace this piece, so I'm not about go through that again to return it. I'm hoping that an additional O-ring in the groove will fill some space to get it to work. Look elsewhere if you can!
