The Ideal 177478 Fan Gasket is a genuine replacement sealing component designed for use in compatible Ideal boilers that utilise a combustion air or flue fan. It provides a secure, heat-resistant seal between the fan housing and surrounding components.

Function & Purpose

The fan gasket prevents air and flue gas leaks at the interface where the fan mounts to the boiler casing or flue pathway. A proper seal supports correct airflow control, improves combustion efficiency, reduces noise and vibration, and helps maintain safe operation by preventing unwanted gas escape. Replacing a worn, cracked, or degraded fan gasket helps restore airtight sealing and reliable fan performance.

Compatibility

This fan gasket is engineered to match original equipment specifications for compatible Ideal boiler models that require the 177478 part. It ensures accurate fitment and dependable performance when installed in the appropriate system.

Build Quality

As an authentic Ideal spare part, the 177478 Fan Gasket is manufactured to high quality standards. The materials are selected for heat resistance, durability, and long-term reliability under the thermal and mechanical stresses typical of combustion air and flue fan applications.

Ideal Applications

This fan gasket is ideal for heating engineers, service technicians, and installers performing maintenance, servicing, or part replacements on compatible Ideal boilers. It is particularly useful when air leaks, reduced combustion performance, unusual fan noise, or vibration indicate that the existing gasket may be compromised, helping to restore efficient, quiet, and safe operation.
