Plastic pipes
They are used on vehicles with air spring suspension for connecting the air springs to the integrated control unit and for
controlling the braking corrector.
In the case of replacement, keep in mind that plastic material is not permitted:
- in areas where the temperature could exceed 80
°
C, (e.g. within 100 mm of the engine exhaust system);
- between the chassis and moving parts, where the use of specific flexible pipes is necessary.
The operations must include:
- materials and dimensions Standards DIN 73378 and 74324
(Maximum operating pressure 11 bar)
- curvature radiuses: min. 6

Preparation and assembly
Cut the pipe at a right angle (maximum error 15
°
) using a specific tool, in order to prevent imperfections that compromise the
seal.
In an indelible manner (using tape or ink), mark the length section L (see Figure 2.27) that must be inserted in the union to guarantee
a secure seal. Mark the pipe to prevent assembly errors when performing future work.
