What it is
This is a Vaillant gasket, part number 0020173394, for Vaillant boilers. It is a sealing component, and the fitment list below shows the ecoTEC VU GB boiler models it is listed against.
Signs this part needs replacing
- Water or staining visible at the joint where the gasket sits
- Leaks that return after the joint has been tightened
- Drops in system pressure with no other obvious cause
- Damp or marks around the boiler casing or connections
Before you order
- Check the model number on the boiler's rating plate against the fitment list above.
- Compare the part number on the old gasket, or on any paperwork, with 0020173394.
- Confirm the gasket position on the boiler before fitting, as the fitment list does not describe the location.
