What it is
This is a venturi gasket supplied under part number 5142367 by Potterton for Potterton Commercial appliances. It seals the venturi assembly within the gas and air train of the boiler, maintaining a gas-tight joint at that connection point. The gasket is listed as a gas boiler spare for the Potterton Commercial Sirius FS range.
Signs this part needs replacing
- Visible cracking, hardening or perishing of the gasket material
- Combustion readings drifting outside the expected range for the appliance
- Whistling or unusual noise from the venturi or gas and air train area
- Soot or staining around the venturi joint indicating a poor seal
- Gasket deformation or flattening found when the venturi is removed for inspection
Before you order
- Confirm the appliance model is one of the Sirius 2 or Sirius 3 FS variants listed
- Verify the existing gasket part number against 5142367 before removal
- Check the venturi assembly and its mating faces for damage or distortion
- Confirm the boiler is isolated and made safe before any work on the gas and air train
