Expansion hose for servo line, suitable for Bus T3 Diesel

Replacement for defective expansion hoses or absolutely necessary for retrofitting a power steering.
This expansion hose has the function of a pressure reducer and reduces the pressure peaks that occur when turning the steering to the stop and by the different high speeds.
Without the expansion hose, the overpressure valves in the steering gear would open in this case and a loud snoring noise would occur, which would significantly shorten the service life of the steering gear.
