What it is
These are Viessmann gaskets, supplied under part number 7823871 and listed as gaskets from 14.01.2005. They are sealing components used on Viessmann Vitodens 100 and Vitodens WB1A gas boilers, forming a seal at the joint where they are fitted. The date reference in the part description identifies the appliance build date from which this gasket applies.
Signs this part needs replacing
- Weeping or a visible water trace at the joint the gasket seals
- Gasket hardened, brittle or cracked when inspected
- Flattened or distorted sealing face that no longer sits correctly
- Damp staining or corrosion around the mating surfaces
- Intermittent leakage that appears as the boiler heats up and the joint expands
Before you order

- Check the boiler serial number where the fit list specifies one
