Bong isolator for all generations of La Pavoni manual lever machines that have a bolted-on group head.  This will cool down the group head temperature and also eliminate the need to wait for the group head to cool down between pulls.

See video below of a demonstration of the advantages of the bong isolator:

Kit includes:

• Isolator bong; CNC machined from high heat and shock resistant polymer;
