What it is
A pack of ten O-rings (packing rings) manufactured by Vaillant under part number 981166. These seals are used at joints and connections on a range of Vaillant gas boilers, including Combicompact, Ecomax, Thermocompact and Turbomax models. They provide a tight seal at the point of fitment to prevent water or gas loss.
Signs this part needs replacing
- Visible water weeping or dripping from a joint where the O-ring sits
- Damp staining or corrosion around the connection
- The O-ring has hardened, flattened or cracked with age
- The seal has been disturbed during servicing and will not reseat cleanly
- A joint that continues to seep after tightening
Before you order
- Confirm your appliance model against the fit list above
- Check the part number 981166 against the manufacturer's parts list for your boiler
- Inspect the removed O-ring and compare it with the new seal before fitting
- Confirm how many seals the job requires, as this pack contains ten
