- Liquefied petroleum gas cylinders cannot be filledBecause each cylinder has a certain pressure. The liquefied gas is normally filled into the bottle in a liquid state at a normal temperature, and when the ambient temperature is raised, part of the liquid is converted into a gas to increase the pressure inside the bottle.
