Ideal Flanged Elbow 3 Inch Super 4 173939

The Ideal 173939 is a 3 inch flanged elbow forming part of the pipework assembly on Ideal Super 4 commercial boiler plant. It is a cast flanged fitting that changes the direction of flow through the connected pipe run, with a bolted flange face at the joint rather than a threaded or welded connection. As a Super 4 component it sits within the Ideal Commercial spares range and is listed against the commercial appliance group.

• Visible weeping or a steady drip from the flange joint under normal running conditions
• Rust staining, scale tracking or water marks around the flange face and bolt holes
• Corrosion pitting or thinning on the elbow body, particularly where it meets the flange
• Hairline cracking or distortion at the bend radius after thermal cycling
• Repeated gasket failures at the same joint, which can point to a distorted or damaged flange face

• Check the appliance model and serial plate against the compatibility list to confirm the Super 4 variant
• Inspect the mating flange and bolts at the same time, as these are often disturbed when the elbow is removed
• Have a replacement flange gasket or seal ready, since the joint will need to be remade
• Work on commercial boiler plant should be carried out by a competent engineer, with the appliance isolated and drained before the joint is broken
