Ideal Flange 177958

The Ideal 177958 is a flange supplied as a spare for Ideal commercial heating appliances. It forms part of the connection and mounting arrangement within the appliance assembly, where a secure, correctly aligned joint is needed between mating components. The part is listed under the alternative number 4038504 and is held against the Ideal Domestic Boiler Spares brand line.

• Weeping or visible water tracking at the flange joint, particularly after the appliance has reached operating temperature.
• Corrosion, pitting or surface loss on the flange face, which prevents the joint from sealing evenly.
• A joint that continues to seep after re-torquing, indicating the flange face is no longer flat or true.
• Distortion or mechanical damage found when the joint is opened up during routine service or repair.
• Repeated gasket failure at the same joint, which often points to a damaged or uneven flange face rather than the seal itself.

• Confirm the appliance model and serial number against the compatibility list, as Ideal commercial ranges use several similar flanges across different assemblies.
• Cross-check the alternative number 4038504 against the number marked on the existing part or listed in the appliance documentation.
• Check whether a gasket or seal is required for the joint being worked on, as these are normally replaced at the same time as the flange.
• Work on commercial heating appliances should be carried out by a competent engineer in line with the manufacturer's instructions.
