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 the wear condition, 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 11.2.2 "Replacing 1st generation external sensor with a 2nd generation sensor",
page 72).
