What it is
The Ideal 172225 is a flat sealing washer with a 56mm outside diameter, a 42mm inside diameter and a 2mm thickness. It is a service part for Ideal Commercial Concord ES series appliances, where it sits between mating faces and forms a seal at the joint it is fitted to. The washer is a consumable item: once compressed and aged it is normally renewed whenever the joint is disturbed.
Signs this part needs replacing
- A weep or drip at the joint the washer seals, often showing as staining, crusting or damp around the mating faces.
- The washer is visibly flattened, hardened or cracked when the joint is opened.
- Perished or brittle rubber that no longer springs back when pressed.
- Scale or corrosion debris embedded in the washer face, preventing it from seating cleanly.
- A joint that continues to seep after being re-tightened, indicating the washer has taken a permanent set.
Before you order
- Confirm the appliance model against the compatibility list, as the same washer is used across several Concord ES variants.
- Check the dimensions of the washer being removed: 56mm outside diameter, 42mm inside diameter, 2mm thick.
- The alternative number 1178608 may appear on older documentation or parts listings for the same item.
- If the joint also uses an O-ring or gasket, check whether that item needs renewing at the same time.
