What it is
The Ariston 570177 is a flange gasket used on Ariston gas boilers. It seals the joint between mating flange faces, preventing water or flue gas leakage at that connection. It is listed for the SE, SEN, ST and STN appliance families shown below.
Signs this part needs replacing
- Visible water weeping or staining around the flange joint
- Gasket material cracked, split or deformed
- Gasket hardened or flattened, losing its sealing compression
- Corrosion or scale build-up on the flange faces where the gasket seats
- Repeated pressure loss traced to the flange connection
Before you order
- Confirm your boiler model against the fitment list above
- Check the part number on the existing gasket or in the manufacturer's parts list
- Inspect the flange faces for pitting, corrosion or distortion before fitting
- Compare the old gasket against the replacement to confirm it seats correctly
