Length-compensation fitting
In rail vehicle manufacturing, complex vehicle designs and limited installation spaces require flexible solutions for installing compressed air systems. VOSS length-compensation fittings (LAV) were specifically developed to reliably compensate for axial manufacturing, assembly, and installation tolerances within line systems.
Efficiently compensate for tolerances. Simplify assembly processes.
In modern rail vehicles, high quality requirements meet complex assemblies and tight spaces. Manufacturing and assembly tolerances cannot always be completely avoided. VOSS length-compensation fittings allow for flexible adaptation to actual installation conditions and enable efficient management of axial tolerances within the compressed air system. This simplifies installation procedures and reduces the need for rework.
Thanks to their integrated expansion compensation feature, they enable the secure connection of lines even under challenging assembly conditions. This reduces the need for time-consuming line adjustments and makes assembly processes more efficient. The result is greater process reliability and less effort required for adjustments during vehicle assembly.
