Serto - The radial principle
The SERTO radial system is unique. Thanks to this design, the tube connections can be assembled and disassembled in the easiest way. This saves time and money, as all parts can also be used for repeat assembly, seeing that nothing is bent or damaged. Furthermore, the fittings can be easily installed even in the tightest spaces.
Connect and save
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.
Elimination of the body cone
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.
Increased safety and time saving
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.
Utilise the SERTO advantage even at the construction stage
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.
Conical fitting

Disadvantage:
- costs for tube bending
- longer tubes
- reduced KV value

Your benefit:
- shortest possible connection
- minimum costs
- optimum KV value
More tubes in the same space
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.
SERTO modular system
SERTO components can be combined like the elements in a building block set. The basic elements of our standard programme are straight unions, male adaptors with various threads, elbows, panel and banjo unions as well as L, T and cross unions. Together with connecting parts from SERTO, innumerable, individual, compact solutions with metal-to-metal seals are available for prompt delivery.
Connection option 1 (illustration left outlet)
Connecting part replaces the compression ferrule – instead of the standard compression ferrule use
- Reduction compression ferrule, in order to reduce by up to 2 dimensions
- Plug, to temporarily close off the line
- Tube stub, as replacement for a short tube section
Connection option 2 (illustration bottom outlet)
Connecting part replaces compression ferrule and union nut – instead of nut and compression ferrule use
- Male adaptor, to change to other thread types and sizes
- Female adaptor, to change to other thread types and sizes, as well as from external to internal thread
Connection option 3 (illustration right outlet)
Connecting part is mounted on the SERTO standard connection and acts as a tube – in addition to the SERTO standard connection use
- Hose nozzle, to connect a hose
- Adjustable nipples with an imitation tube socket for an adjustable connection
- Reduction unions, to connect smaller tube diameters
