The SERTO radial system is unique. Thanks to this design, tube connections can be easily installed and disassembled. This saves time and money, because all of the components can be re-used, as nothing will be bent or damaged. In addition, the screw fittings can also be easily installed in very confined spaces.
The price for a tube system is determined by 3 factors: the fittings, the tube and the assembly time. If the tube system has to be dismantled, with SERTO you can save 30 % of the costs due to the inverse sealing function of SERTO clamping ring screw fittings.
With all common tube fittings, the tube is inserted into the body of the fitting and is sealed with a cone-shaped clamping/cutting ring. SERTO also uses cones, but in contrast to all other tube fittings, this is not in the body of the fitting, but rather in the nut. This results in the great advantage that the seal of the clamping ring to the body of the screw fitting is by means of a plane surface. Components which are included in a tube system can therefore be radially removed from the system.
For dismantling or reassembly, only the nuts of the relevant screw fitting need to be loosened. The component can be removed without bending the tube or loosening other sealing points. In contrast, with conical screw fittings, the tubes are inserted into the body, which prevents easy removal. In some cases, several sealing points must be opened and then screwed back together and sealed. For more rapid assembly, the tubes can be pre-assembled with a nut and clamping ring and inserted radially into the piping network. This is also not possible with a conical screw fitting.
The replaceable connection of two containers can also be implemented with a conical fitting. For this, the tube must make a 180° bend, so that the assembly can be removed to one side (1). With SERTO screw fittings, the containers are connected directly by the shortest route (2). This means shorter tubes, no work for the tube benders and better flow rates. In addition, a straight replacement tube is far easier to obtain than a specially bent tube.

Because with SERTO the tubes do not penetrate into the body of the fitting, but rather are only in front of it, the body can be one or two spanner sizes smaller than with a conical fitting. If the body is smaller, so are the nuts. The few millimetres which are saved make a big difference. More tubes can be installed in parallel in the same space.
