What it is
The Ideal washer 4035904 is a sealing component supplied under part number 178055. It sits between mating faces in the appliance assembly, where it compresses to close the joint and stop water escaping past the connection. It is used across the Ideal commercial Evojet range.
Signs this part needs replacing
- Water weeping or a visible drip at the joint the washer seals
- Staining, scale trails or corrosion around the mating faces
- The washer has hardened, flattened or cracked with age and no longer compresses
- A joint that continues to seep after the assembly has been tightened
- The washer is deformed, split or missing when the joint is opened for service
Before you order
- Check the appliance model and serial number against the compatibility list to confirm the washer is correct for your unit
- Compare the number on the existing washer with 4035904 before ordering
- Confirm how many washers the joint requires, as some assemblies use more than one
