What it is
This is a Viessmann O-ring with a 316mm internal diameter, supplied under part number 7817185. It is a sealing component used on Viessmann Vitodens 200 WB2 series appliances, where it forms a watertight joint at the mating face it sits in.
Signs this part needs replacing
- Water weeping or dripping from the joint the O-ring seals
- Visible flattening, hardening or cracking of the ring material
- The ring sitting loose, distorted or partly out of its groove
- Traces of scale or corrosion staining around the sealing face
- Repeated pressure loss that persists after the joint is re-tightened
Before you order
- Confirm the appliance model and serial number against the fitment list
- Measure the existing O-ring or check the internal diameter marked on the part
- Inspect the sealing groove and mating face for damage before fitting
- Check the O-ring is seated correctly and not pinched during reassembly
