Ideal Copper Washer Aeromatic 152426

The Ideal 152426 is a copper washer used on the Aeromatic assembly of Ideal domestic boilers. Copper washers of this type form a soft, deformable seal at a joint, compressing under load to close the gap between mating faces and stop water or pressure escaping. It is a service item, so it is normally replaced whenever the assembly it sits in is opened up.

• Weeping, damp staining or a bead of water at the joint the washer seals
• The washer face is flattened, hardened or visibly deformed from repeated compression
• Green or white corrosion deposits on the copper surface
• System pressure dropping and topping up needed more often than usual
• Scale or debris trapped on the sealing face after the assembly has been disturbed

• Check the GC number on the appliance data badge against the numbers in the compatibility table below.
• Confirm the number on the existing washer matches 152426 before ordering.
• Note the alternative number 1176980, which may appear on older paperwork or listings for the same item.
• Inspect the other seals and washers in the same assembly and renew them at the same time where they show wear.
