Trangia Spare Screw cap for Trangia spirit stoves, with rubber washer

Screw cap for Trangia spirit stoves. Can be used for extinguishing the burner , but first remove the rubber washer from inside the cap as this may melt when extinguishing the burner. (Note, do not screw the burner cap on tightly to the burner whilst the burner is still warm, as when it cools down the cap will become very difficult to remove )
