NOTICE
Increased wear due to incorrect installation
With tubes that rest on the edge of enclosures, there is an increased chance of wear due to
vibrations. This might lead to leakages.
– PA tubes need to be installed such that they neither exercise tensile or compressive stress on
connections nor rest on the rim.
– Avoid excess lengths to prevent undesired vibrations.
– Avoid moisture in the PA tube or at the pressure port of the external sensor.
1. Hold the PA tube with the connection to the tire valve.
2. Hold the other end of the PA tube to the external sensor.
3. Mark the position on the tube where the PA tube sits flush with the edge of the external sensor
(e.g. using adhesive tape).
4. Cut the PA tube (WABCO part number: 960 731 800 0 bis 960 731 802 0) to the required length if
necessary.
Make sure that the PA pipe is 20 mm inside the connection. For this purpose, the PA tube should
be cut 20 mm behind the marking.
Use a cutting tool suitable for right-angled shortening, such as that used for shortening plastic
brake lines.
5. Mount the connecting tube to the external sensor by inserting the end of the PA tube into the
external sensor opening.
Ö After pressing with force, the PA tube is locked in position and can then only be removed again
after unscrewing the brass screw connection (WABCO part number: 893 770 005 2).
