Components
Connecting tube
The external sensors must be permanently connected to the tires for sensing
tire pressures. Use WABCO pre-assembled PA tubes for this purpose. The
connection does not have to be disconnected for inflating the tires as valves for
inflating the tire are located on the external sensors.
Depending on wear situation, a replacement of the PA tube is recommended
after 1,000,000 km.
Various types of PA tubes are illustrated in the chart:

Check PA tubes frequently for damages and replace them if necessary.
Replace defective hose connections with PA tubes. Fit a new external sensor at
the same timesee chapter "10.2.2 Replacing 1st generation external sensor
with a 2nd generation sensor" on page 63.
Rubber hoses can be fitted in vehicles installed with OE equipment. Before
replacing the hoses, observe the release notes of the manufacturer.
