What it is
The Ideal 003381 is an M8 Form A washer with a zinc-plated finish, supplied as a spare for Ideal commercial boiler appliances. Form A is the standard flat washer pattern, used under a bolt or nut to spread the clamping load and protect the joint face it bears against. On the Concord family it forms part of the sealing arrangement at bolted connections, helping keep the joined components tight and leak-free.
Signs this part needs replacing
- Weeping, damp staining or a visible drip at a bolted joint on the appliance
- White rust, pitting or heavy corrosion across the washer face
- The washer is flattened, cracked, split or visibly deformed
- Water tracking along a stud or bolt thread from a joint that will not pull down tight
- Reassembly of a component where the original washer has been lost or crushed
Before you order
- Confirm the model and GC number from the appliance data badge before ordering
- Check the compatibility list to confirm the washer suits your exact Ideal model
