1, Braid
Provided with a steel wire braid, the pressure resistance can be increased by different degrees (type A, B or C). A mechanical joint
is realized between the two end fittings, blocking the uncontrolled elongation of the metal hose assembly under pressure forces.
These braids are made of high quality chrome-nickel steel 1.4301 (equivalent to AISI 304).

As a mechanical protection in heavy duty conditions, the metal hose assembly may be additionally equipped with a wire spiral
and/or a protecting hose. Provided at both ends with spirals against buckling, the bend stress may be further reduced.

2, Length tolerances
The tolerance of the overall length of a metal hose assembly ranges between ?1% and +3%

3Bend radius
Radius measured at the longitudinal axis of the metal hose. The ISO standard distinguishes between static bend radius ? for
single movement (bend test) ? and dynamic bend radius ? for frequent movement cycles and/or pressure impulses (fatigue test).
Falling below the minimum bend radius shortens the life time of the metal hose assembly.
