What it is

The Ideal 180762 is a hydroblock gasket kit, Base 2 variant, produced by Ideal for use across its combi and heat-only boiler ranges. The hydroblock carries domestic hot water and heating water through the diverter and hydraulic section of the appliance, and this kit provides the seals that sit between the hydroblock body and its mating components. Its job is to keep water contained at each joint under normal operating pressure and temperature cycling.

Signs this part needs replacing

  • Water weeping or dripping from the hydroblock joints
  • Damp staining, scale trails or corrosion around the hydroblock body
  • Gaskets found flattened, hardened or cracked when the assembly is opened
  • System pressure dropping with no leak visible elsewhere on the appliance
  • Debris or scale sitting on the gasket faces during a routine service

Before you order

  • Check the GC number on the appliance data badge against the compatibility list to confirm the model
  • Confirm the part number 180762 and the Base 2 variant before ordering
  • Inspect the hydroblock mating faces for scoring or distortion while the old gaskets are removed
