What it is

The Ideal 170256 is a return flange and pipe gasket used on Ideal commercial heating appliances. It seals the joint between the return flange and the connecting pipework, keeping the water circuit tight at that connection. The gasket is manufactured by Caradon for Ideal and is used across the Ideal Commercial range, including the Viceroy GT family.

Signs this part needs replacing

  • Water weeping or dripping from the return flange joint
  • Damp staining, scale or corrosion around the flange and pipe connection
  • Gasket hardened, flattened or brittle when the joint is opened
  • Visible cracking, splitting or deformation on the gasket face
  • Leaks returning after the joint has been re-tightened

Before you order

  • Confirm the appliance model and part number 170256 before ordering.
  • Check whether the earlier numbers 82298922 or 1177497 appear on the existing part or on your documentation.
  • Inspect the flange faces while the joint is open, as a scored or pitted face may need attention alongside the gasket.
