Cold-formed tube
The cold-forming of the tube is carried out by the EO2-FORM machine. Machine operation and tool
set-up are optimised for short cycle times, which makes the process easy and fast. The tube is
connected when the sealing ring is fixed and the nut is tightened.
The working contact area of the EO2-FORM connection is the flat front surface of the metallic support
ring which is made of heat-treated, high-strength steel. This provides superior mechanical strength
without settling, loosening or need for re-tightening.
Advantages & Benefits of the EO2-Form fitting system
Highest Pressure Performance: Due to the application of even better materials combined with the
special processing of individual components, EO2-FORM can be used in applications of up to 800 bar
(S series) and 500 bar (L series).
EO-FORM considerably exceeds the DIN/ISO requirements and guarantees a 4-fold design factor.
Thanks to the higher pressure levels, less expensive "L" series fittings can now be used instead of the
heavier "S" series, which also is of benefit in limited or tight space applications.
Sealing capability: The high volume elastomeric seal forms the primary sealing element, thus
assuring leak-free sealing. Even low-viscosity media such as water or gas are hermetically sealed.
Hydraulic systems therefore do not "sweat" at the fitting joints.
Universal: The EO2-FORM machine can cold-form all common steel tubes used in hydraulic systems
(the EO2-FORM process also allows the use of stainless steel and exotic materials such as CuNiFe;
please ask for separate catalogue). EO2-FORM tools cover metric tube from 6 to 42 mm OD. Thin wall
tube of 1 mm wall thickness can be processed, too.
Superior vibration resistance: The new EO2-FORM process achieves a smooth structural
transformation of the tube wall allowing superior vibration resistance.
Durability: The elastomeric seal does not require any re-tightening even after years of operation
under severe working conditions.
Efficient: Compared to welding or brazing, EO2-FORM is much less time consuming. Special tube
preparation and finishing are not necessary. Forming uses only a fraction of the energy needed for
brazing or welding.
Quality: Tube clamping and tooling are fully automated. Therefore, high and consistent quality is
achieved without manual adjustment.
