What it is

The Worcester Bosch 5484164 is a main gas orifice with a 3.40mm drilled hole. It is a metering component that sits in the gas train and sets the gas flow rate to the burner. The drilled hole size determines the volume of gas passed through to the appliance.

Before you order

  • Confirm the appliance requires a main gas orifice with a 3.40mm drilled hole, as the hole size sets the gas rate.
  • Cross-check the part number 5484164 against the manufacturer's documentation for the appliance.
  • Compare the part number against the component being replaced to ensure the correct orifice size is fitted.
