What it is
This Alpha gasket measures 18.5 mm x 11.5 mm x 2 mm and is supplied as part number 1.034405. It is a flue component used across the Alpha InTEC 2, E-TEC, ECO 2 and Evoke gas boiler families. The gasket seals its joint within the flue assembly, helping to maintain a gas-tight path for products of combustion.
Signs this part needs replacing
- The gasket is cracked, brittle or flattened when inspected
- Staining or discolouration around the flue joint suggests a seal is failing
- Combustion readings fall outside the expected range for the appliance
- A smell of flue products is noticeable near the joint
- The gasket is missing or has shifted out of position during service
Before you order
- Confirm your boiler model and GC number against the fitment list above
- Compare the dimensions with the gasket removed from the appliance
- Check the manufacturer's instructions for any additional seals or fixings required at the same joint
- Isolate the appliance before starting work
