So you’ve used butane gas (the blue bottles) all summer but now feel like touring all year. Did you know that Butane freezes at temperatures approaching zero degrees so is of little use during cold spells.
For winter touring you require propane (the red bottle) as this can easily cope with british extremes. If your caravan is fitted with a built-in regulator you don’t need to change the whole thing, just the pigtail (the section of pipe from regulator to gas bottle).
This is a propane pigtail fitted with 450mm of gas hose to enable you to the job yourself (please take care, it is gas!)
