Trangia Spirt Burner with screw cap & simmering ring. This is a genuine Trangia Spirit Burner & it has done the job of powering the Trangia stove systems for a very long time. It is a proper piece of old school technical engineering that is stupidly robust & extremely reliable. Trangia have over 80 years of experience in making their stoves & for the last 50 years or more they have been the choice storm-proof stove for outdoor goers. Thats because this kit has been tried, tested & trusted for generations; the Trangia Factory is basically on the on the doorstep of the Scandinavian wilderness so its pretty safe to say that they know what they are doing. Why do people buy Trangia? Its because they are that simple they cant really go wrong. There are almost no moving parts that can break; you may need to replace the burner cap seal every few years & buy a new kettle because you have misplaced it or its getting a bit tatty, but thats about it.
