PTFE Flow Restrictor Washer 1.8 x 18.2 x 1 mm for Brew Group Temperature Control
(Replaces 2.5mm and 2mm version – Backwards compatible for all Expobar/Ruggero/Crem models)

This PTFE flow restrictor washer is used in single boiler commercial espresso machines to regulate brew group temperature by controlling water mixing. The precision 1.8 mm orifice limits water flow at the rear of the brew group, allowing controlled blending of incoming water to achieve stable and optimal extraction temperature. This function is critical in systems where temperature balancing is achieved through passive hydraulic restriction rather than active electronic control.

  • Controls brew group temperature via calibrated water restriction
  • 1.8 mm orifice regulates flow for precise thermal mixing
  • Installed at the rear of the brew group in single boiler systems
  • Supports consistent espresso extraction temperature
  • Used in maintenance or replacement of worn or scaled restrictors
  • Type: Flow restrictor washer / dosing jet
  • Material: PTFE
  • Orifice Diameter: 1.8 mm
  • Outer Diameter: 18.2 mm
  • Thickness: 1 mm
  • Application: Brew group temperature control in single boiler espresso machines

This component is essential for technicians servicing temperature-controlled brew groups in commercial espresso machines. Correct sizing and clean installation are critical to maintaining proper thermal balance and consistent espresso performance in café environments.
