What it is

The Ideal 179455 is a sump cover gasket kit manufactured by Ideal for their Commercial range of heating appliances. It is designed to seal the sump cover on the heat exchanger, creating a watertight joint that prevents water or coolant from escaping. The kit is suitable for appliances with a power rating between 100kW and 150kW. Over time, heat and water exposure can cause the gasket to harden or crack, so replacing it is essential for maintaining system efficiency and preventing leaks. This kit is a direct replacement for the original sump cover gasket, ensuring a proper fit and reliable sealing performance. It is recommended to replace the gasket whenever the sump cover is removed.

Signs this part needs replacing

  • Water or coolant leaks around the sump cover joint
  • Visible hardening, cracking or deterioration of the gasket material
  • Overheating or pressure loss in the heating system
  • Corrosion or scale build-up on the sealing surfaces
  • A failing gasket can lead to water damage and reduced system performance

Before you order

  • Check your appliance model and serial number against the compatibility list.
  • Confirm the part number 179455 matches your requirement.
  • A gasket kit is required for the sump cover.
  • If unsure, consult a qualified heating engineer.
