SCREWCAP W/ O-RING

The SCREWCAP with O-RING is an essential component for the Trangia Spirit Burner. It features a twist-on cap with an o-ring that efficiently seals the burner, preventing fuel evaporation and eliminating the need to empty unused fuel between uses. This results in less fuel wastage, making it perfect for extended use. The SCREWCAP also comes with a simmer ring that adjusts the burner's flame from full to simmer, adding to its versatility and user-friendliness.
