The Steam Nozzle connects threads onto the Steam Pipe to connect the Milk Frother/Water Pipe. If not properly maintained, milk deposits will accumulate, causing a blockage. Lubricate the O-Ring regularly to prevent it from hardening/cracking.
Please Note: This nozzle connects the hot water pipe on the Jura ENA 9, XJ5-XJ6-XJ9 models. It is NOT used to connect the Dial Component or Frothers.
