Just checking out the competition and saw this burner - nothing wrong with the burner but the white part on the end looks very much like plastic/derlin. https://www.hobbysteam.com/store/4-burner-only-120mm.html?fbclid=IwAR11W7uXh3ovgd4dpfHFmHb-g8uynmTDTDxcLXqEglVoC0iYbI2YCHFsgQU

More likely a machineable ceramic, surely.

How hot would you expect that part to get, Fizzy ?

I note the push-fit connector is not far away.

Why not buy yourself one and then you can play with it to your hearts delight and see first hand what the plastic looking bit is, as you are a business I am sure you can put it through the books.

Maybe derlin is heatproof?

Is the white part not an insulator or thermal break so the heat does not transfer down the tube supplying the gas?

I was under the impression that in a properly functioning burner, the flame does not touch the orifice from which it emerges, so the heat transfer to the aluminium part is through the surrounding atmosphere. In that respect the aluminium is a good choice as its thermal mass, high surface area and good conductivity will keep it cool. Short of copper (not easily found in box section), what would be better?
