What it is

The Ideal 176728 is a 1 1/2 inch nut and gasket assembly used on Ideal heating appliances. It forms the threaded, sealed connection at the point where a pipe or fitting meets the appliance body, with the gasket providing the compression seal against the mating face. It is listed under Ideal's bolts, nuts and screws category and is used across Ideal Commercial and Ideal Solar Thermal equipment.

Signs this part needs replacing

  • Weeping or visible water tracking at the nut joint, especially after the system has heated and cooled
  • Damp staining, crusting or limescale build-up around the threaded connection
  • The gasket has hardened, flattened or cracked and no longer compresses to seal
  • The nut has corroded, cross-threaded or been over-tightened and will not pull down cleanly
  • Repeated small pressure losses traced to a joint rather than to the appliance internals

Before you order

  • Confirm the appliance model and, where available, the serial number against the compatibility list before ordering
  • Check the existing nut and gasket size on the appliance, as 1 1/2 inch fittings are not interchangeable with other thread sizes
  • Inspect the mating face for pitting or damage, since a new gasket will not seal against a scored surface
