What it is
The Ariston 3740846 is a sheet gasket measuring 24 mm x 17 mm x 2 mm and carrying a 3/8Z K size designation. It seals a mating joint on Ariston Genus Premium EVO HP boilers and Kairos MACC cylinders, preventing water loss at the connection.
Signs this part needs replacing
- Water weeping or dripping from the joint the gasket seals
- Visible cracking, splitting or deformation of the gasket material
- Gasket hardened or flattened, losing its sealing compression
- Scale or corrosion staining around the mating faces
- Repeated pressure loss traced back to the sealed connection
Before you order
- Confirm your appliance model against the fit list above
- Measure the existing gasket and compare it with 24 mm x 17 mm x 2 mm
- Check the 3/8Z K size designation matches the connection being sealed
