What it is

The Potterton 577373 is a thermowell, also described as a thermostat pocket, measuring 100mm in length with a 1/2 connection. It forms part of the Potterton Commercial spares range for commercial boiler applications. The thermowell provides a pocket into which a thermostat or temperature sensor sits, keeping the sensing element in contact with the medium being measured while isolating it from the system.

Before you order

  • Confirm the thread size and immersion depth match the thermostat or sensor being fitted.
  • Check the existing thermowell length and connection against the dimensions given here.
  • Verify the part number against the appliance documentation before ordering.
