What it is

These are O rings for the domestic hot water (DHW) heat exchanger. Manufactured by Ideal, they seal the heat exchanger connections on compatible Ideal boiler models. The O rings prevent water leaks at the heat exchanger joints.

Signs this part needs replacing

  • Water leaking from the heat exchanger connections
  • Visible cracking, flattening or hardening of the O rings
  • Recurring pressure loss in the heating or hot water system
  • Scale or debris build-up on the O rings
  • Dampness or corrosion around the heat exchanger joints

Before you order

  • Check your boiler model against the Fits list above
  • Confirm the part number 075401 matches your requirement
  • Inspect the heat exchanger connections for damage before fitting new O rings
  • Ensure the system is depressurised and drained before replacing the O rings
