What it is

This is the PCB gasket, manufacturer part number 5142171, produced for Potterton Commercial appliances. It is a sealing gasket that sits against the printed circuit board assembly in Potterton Commercial Sirius 2 and Sirius 3 boilers, protecting the board area from moisture, dust and airborne debris.

Signs this part needs replacing

  • The existing gasket is split, flattened or perished when the PCB housing is opened
  • Moisture or dust ingress is visible around the printed circuit board enclosure
  • Traces of water staining or corrosion on or near the board
  • The gasket no longer sits correctly in its channel and cannot be refitted

Before you order

  • Confirm the appliance model against the Sirius 2 or Sirius 3 fit list above
  • Check the part number on the existing gasket or the appliance data plate before ordering
  • Inspect the PCB housing for distortion or damage that could prevent a correct seal
  • Check whether any other gaskets or seals in the housing also need replacing at the same time
