Which GOK products can I use to replace DuoControl or DuoComfort from Truma after ten years?
Wearing parts of the gas system in motor caravans or caravans must be replaced by the camper after ten years from the date of manufacture at the latest. These include, in particular, gas pressure regulators or changeover valves. In existing systems, you often find designations on the components such as DuoControl or DuoComfort. We’ll tell you which products from the Caramatic line from GOK can be used as a replacement.
It has now been discussed on most of the campsites in Germany: after ten years from the date of manufacture at the latest, for example, gas pressure regulators and gas hoses have to be removed from the gas systems of camping vehicles and new ones have to be installed.
A DuoControl or DuoComfort from the manufacturer Truma is often installed in existing systems for the stationary operation of gas heating, fridges and similar at the campsite. However: Can you easily replace these Truma products with products from GOK? And if so, which ones are they?
Some Caramatic line components are only suitable for stationary gas supply, such as the Caramatic ProTwo or the Caramatic SwitchTwo.

DuoControl
The DuoControl from Truma is a gas regulation system to operate a two-cylinder system in a motor caravan or caravan. This DuoControl from Truma for stationary operation – Attention! There is also a model for operation while driving. – You can replace it with the Caramatic ProTwo from GOK after ten years.
The highlight: The systems are identical in design and operating principle. This means that only costs for the new product are incurred for the owner of the leisure vehicle. And a cost-effective and less time-consuming one-to-one replacement is possible.
The Caramatic ProTwo is a combination of gas pressure regulator and automatic changeover valve. The advantages of Caramatic ProTwo are:
- Automatic changeover to reserve
- Cylinder replacement without operational interruption
- Visual indicator of which cylinder gas is drawn from
Scrabbling out of the motor caravan or caravan on the muddy ground in the middle of the night in ice-cold and rainy weather, because the cylinder is suddenly empty and the heating has shut down? This is a thing of the past with the Caramatic ProTwo!
You can operate two gas cylinders with the GOK Caramatic ProTwo in the gas system of a motor caravan or caravan. If one cylinder is empty, the automatic changeover valve switches to the reserve cylinder.
DuoComfort
In contrast to its DuoControl, the DuoComfort from Truma is a separate automatic changeover valve. The low pressure regulator is not integrated into the unit; it is installed as a separate component in the piping downstream of the changeover valve.
In other words, the DuoComfort has only one main function: switching between the operating cylinder and reserve cylinder. If the regular replacement is due after ten years, the Caramatic SwitchTwo from GOK (image) can replace an old Truma DuoComfort.
The following also applies here: The two products are identical in terms of design and functioning principle. For this reason, the replacement is associated with little effort and costs.
Due date of replacement
As indicated already, the ten-year period begins with the date of manufacture of the fitting. It doesn’t matter whether this is a GOK Caramatic ProTwo, SwitchTwo, a gas hose or a Truma DuoControl or Truma DuoComfort. For example, the installation of gas system components is not relevant to the replacement time.
