What it is

The Ideal 174404 is a seal kit intended for the water manifolds on Ideal Commercial Imax Xtra boilers. It provides the sealing components that sit at the manifold joints, where the water-carrying sections of the appliance are bolted together. Over time these seals harden, flatten and weep, so the kit is the standard replacement when the manifold assembly is stripped down for inspection or repair.

Signs this part needs replacing

  • Water weeping or dripping from the manifold joints, often showing as crusting or staining around the connection faces
  • A persistent damp patch or corrosion marks beneath the water manifold area of the boiler
  • Seals that are visibly flattened, cracked or hardened once the manifold is opened up
  • Scale or debris trapped in the seal grooves, causing an imperfect seat after reassembly
  • Repeated pressure loss that traces back to the manifold joints rather than the system pipework

Before you order

  • Confirm the appliance model and serial number against the compatibility list, as the Imax Xtra range covers several output sizes
  • Check the part number on the existing component or in the manual; 1780380 is the same item listed under an alternative number
  • If the manifold is being disturbed for another repair, replace the seals at the same time rather than reusing the old ones
  • Have the boiler isolated and drained before work begins, and follow the manufacturer's instructions for manifold removal and torque settings
