What it is
The Vaillant 0020180080 is a gasket supplied in a pack of 10. It is fitted to the Vaillant aroTHERM VWZ MWT 150, where it seals a connection and prevents water loss at the joint.
Signs this part needs replacing
- Water weeping or a visible drip at the joint the gasket seals
- Scale, staining or corrosion around the connection
- The gasket feels hard, brittle or flattened rather than pliable
- Cracking or perishing visible on the gasket face
- A joint that continues to seep after being tightened
Before you order
- Confirm your appliance is a Vaillant aroTHERM VWZ MWT 150
- Check how many joints you are resealing, as the gaskets are supplied in a pack of 10
- Compare the old gasket against the new one for size and profile before fitting
