What it is

The DHW plate exchanger gasket is a sealing component for the domestic hot water plate exchanger on Potterton boilers. It is manufactured for Potterton Commercial appliances and seals the joint at the plate exchanger to keep the DHW circuit watertight. The part is supplied under Potterton part number 5138648.

Signs this part needs replacing

  • Water weeping or tracking from the plate exchanger joint
  • Scale or crusty limescale deposits around the gasket face
  • Gasket found hardened, flattened or brittle when the joint is opened
  • Leaks appearing after the plate exchanger has been removed and refitted
  • Staining or corrosion on nearby components caused by a slow weep

Before you order

  • Confirm the appliance model matches Potterton Commercial Sirius SAT Rs2Z
  • Check the existing gasket profile against the part before ordering
  • Inspect the plate exchanger mating faces for scale, pitting or distortion that could prevent a seal
  • Order the quantity needed if more than one joint is being disturbed
