New: The STAUFF Form EVO Tube Forming System

Increased Level of Efficiency and Versatility as the Result of Continuous Optimisation

STAUFF Form EVO Tube Forming System

The STAUFF Form tube forming system was first presented in 2015. Since the beginning it has undoubtedly been one of the most efficient solutions available on the market for connecting metric tubes. In addition to its simplicity, it convinces with a high degree of safety, reliability and reproducibility.

With STAUFF Form EVO, STAUFF now presents the latest generation of the tube forming system, which is characterised by an increased level of efficiency and versatility as a result of continuous optimisation.

STAUFF Form EVO has been designed as standard for seamless cold-drawn precision steel tubes as well as stainless steel tubes with dimensions between 6 x 1.5 mm and 42 x 4 mm in the Light Series and between 6 x 1.5 mm and 38 x 6 mm in the Heavy Series.

If required, parameters for alternative materials are available upon request and can be added by the manufacturer or via the optional cloud connection moduleintegrated in the machines.

Key Benefits of the STAUFF Form EVO Tube Forming System


  • Based on standard components including the standard union nut of the STAUFF Connect product range according to ISO 8434-1 – No duplicate storage
    of similar stocking of similar components with a correspondingly high risk of confusion

  • Positive-locking connection with an elastomer sealing with a particularly large cross-section to provide secure and permanent sealing even in the event of unfavourable tolerances

  • Sealing of the only possible leakage path primarily via the STAUFF Form EVO sealing ring as well as the secondary, face sealing

  • Preservation of the flow behaviour through the optimised shape of the formed tube end

Assembly Tools and Devices

  • Robust table-top device for continuous operation in the workshop

  • High efficiency of the system with low cycle times

  • Optimum tool concept with exchangeable internal tube supports, so that only a small number of tools is required to cover all tube diameters

  • Intuitive operation via touchscreen

  • Optional cloud connection as well as machine briefings and trainings

  • All tools needed for the forming process clearly labelled with the tube dimensions so that assembly errors caused by incorrect assignment can be largely ruled out

  • Short times required for tool changes as clamping jaws, tube shaper and internal tube supports can be simply replaced without the need for any tools

  • Attractive maintenance packages to ensure best possible service

  • Low insertion depths compared to alternative systems for even more complex tube geometries and smaller bending radii

Durability and Application

  • Suitable for both steel and stainless steel tubing as standard – also applicable for alternative tube materials on request

  • Covers all common metric tube dimensions from 6 x 1.5 mm to 42 x 4 mm in the Light Series and 38 x 6 mm in the Heavy Series respectively

  • Suitable for nominal pressures up to 800 bar in the Heavy Series – designed with four-fold safety and maximum tear-out strength

  • The use of FKM (Viton®) as the standard seal material makes the system perfect for the most challenging applications. Thanks to the combined metal-elastomer seal, low-temperature ranges down to -35° C are possible without restriction

  • High-quality zinc/nickel surface coating provides maximum protection and corrosion resistance – standard for all parts in the STAUFF Connect range

Final Assembly

  • Incredibly simple final assembly in the fitting body with low assembly torques as well as short assembly paths (once the fixed point has been reached) with a minimised risk of over-assembly

  • Assembly errors are consistently avoided due to the laterally identical profile of the sealing ring

  • Connections can be untightened as often as required and reassembled without wear, as any damaging expansion of the 24° conical bore of the fitting body is technically avoided

  • No need for time-consuming and expensive training
