There are two groups of Trangia users - one who thinks they'll never accidentally melt the washer inside their meths burner, and one group looking for somewhere to purchase spare washers having inevitably put the cap back on when the burner was too hot.
It's one of outdoor life's certainties that we all end up in the second group, sooner, or later.
This kit of two replacement Trangia washers will keep your meths safe inside your burner when it's in transit.
Stock up now - you never know when you'll need them.
