Ideal Flue Gasket Double Lip Seal 178941

The Ideal 178941 is a double lip flue gasket seal manufactured by Ideal for use on its commercial appliance range. It sits at the flue connection, where the twin sealing lips close off the joint against flue gas escape and condensate weepage. The double lip profile gives two contact faces on the mating flue component, which helps maintain a tight seal where the flue passes through the appliance casing or spigot.

• Visible cracking, hardening or flattening of the sealing lips when the flue joint is inspected
• Soot staining or dark marks around the flue connection at the appliance
• Condensate weeping or damp traces at the flue joint
• A flue gas smell or detectable draught close to the flue spigot
• Flue gas analysis readings that drift or fail to settle during servicing

• Confirm the appliance model and, where available, the serial number so the correct flue seal variant is selected
• Compare the profile of the old seal against the double lip design before fitting, as flue joints differ across the Instinct Heat range
• Check whether the surrounding flue joint components also need renewing while the appliance is open
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
