An aerated gas burner jet comprising a hollow tube with at least one external axial flute the tube being adapted to fit or sit in a port of a burner, preferably a drilled-port bar burner or a circular cast-iron ring burner, so that the flow of gas through the port passes both through the hollow tube and along the flute or flutes. The stability of the gas flames is improved by the provision of a ring or washer transversely disposed to and at least partly blocking the flute or flutes, the ring or washer causing the gas stream to be split into two.
