This Lelit 4 Hole Steam Tip is meant for the Bianca PL162T series where baristas prefer to have a stronger and quicker steaming experience with the double boiler espresso machine. Compatible with Mara Machines but your steam will run out much faster. It can be used on the Mara PL62X and other Mara Machines, Elizabeth PL92T, but as the steam compartments or steam boilers are smaller, you may need to wait longer between froths to allow the pressure to build back up.
