Ideal Silicone Seal Blue 80mm 176589

This is an Ideal silicone seal supplied in blue with an 80mm nominal size, listed under part number 176589. It is a soft sealing component used to close off a joint or connection point on the appliance, preventing water from escaping past the mating surfaces. It belongs to the Ideal spares range covering the Esprit 2 and Evo HE families, along with a number of other Ideal models.

• Water weeping or dripping from the joint the seal sits in, particularly once the appliance has reached working temperature.
• The seal feels hard, brittle or flattened rather than soft and pliable when handled.
• Visible cracking, splitting, perishing or a chalky surface on the silicone.
• Blue colour has faded or the seal has taken on a stained, discoloured appearance.
• Scale or corrosion debris trapped around the seal face, preventing it from seating cleanly.

• Confirm the appliance model and GC number against the compatibility list, as the same seal is used across several Ideal ranges.
• Check the part number on the existing component or in the appliance documentation before ordering, and note the alternative number 1781934 in case it appears on older literature.
• Inspect the surrounding joint while the appliance is open; if several seals in the same assembly are tired, it may be more practical to replace them together.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
