燃料瓶專用蓋

Took this on a muddy weekend trip and the screw closure held up perfectly—not a single drop leaked even bouncing around in the back of the truck. The threading feels solid and tight, exactly what you want when you're hauling fuel over rough terrain.

Finally, a cap that actually seals tight without any fuel smell leaking out. The threading is solid and screws on smoothly every time. Exactly what I needed for my camping trips.

Bought this as a spare for my fuel bottle and it threads on like it was made for it. No drips in my pack after a full day of hiking, which is more than I can say for the cap I lost.
