What it is
The Vaillant 0020231195 is an O-ring used across a range of Vaillant domestic gas appliances, including the HOME, EcoTec and EcoFit families. It forms a fluid-tight seal at the joint it is fitted to, preventing leaks at that connection. It is a service part, intended for replacement during maintenance or repair.
Signs this part needs replacing
- Visible cracking, flattening or hardening of the ring
- Weeping or dripping at the joint the O-ring seals
- Water staining, corrosion or scale deposits around the joint
- The ring has been disturbed during a repair and will not reseat cleanly
- A leak that returns after the joint has been tightened
Before you order
- Confirm the part number 0020231195 against your appliance's parts list
- Check your appliance model against the fit list above
- Inspect the joint itself for damage beyond the O-ring before refitting
