What it is

A Potterton seal for the shut off flap, listed under manufacturer part number 644143. It is the sealing component that sits with the shut off flap assembly, where a sound seal is needed for the flap to close correctly. It is supplied as a single component rather than as part of a flap assembly.

Before you order

  • Confirm the part number 644143 against the appliance documentation or the existing component before ordering.
  • Check the condition and seating of the shut off flap itself, as a worn or damaged flap may need attention alongside the seal.
  • Inspect the old seal on removal and compare it with the replacement before fitting.
