What it is

This is a Potterton gas tube seal, supplied under part number 692229 and identified by the designation SGB 125 -300. It is a sealing component used within the gas-carrying tube arrangement on Potterton gas boilers. The seal forms the gas-tight joint required at the tube connection point, so it is a safety-critical item rather than a cosmetic part.

Before you order

  • Confirm the part number 692229 against the appliance's own documentation or parts list before ordering.
  • Check that the designation SGB 125 -300 matches the seal called for on the appliance.
  • Inspect the existing seal and its seating for distortion, hardening or contamination, as these affect how well a new seal will seat.
  • Gas-carrying joints must be reassembled and tested by a competent, registered engineer in line with current UK gas safety requirements.
