Polyamide (PA) nylon tubing for
air brake
Your vehicle is fitted with latest
generation polyamide (PA) nylon
tubing for air brake.
PA material is preferred for this
application for :
●
Excellent chemical resistance
(against fuel, battery acid,
hydraulic oils etc.)
●
Dimensional stability and impact
resistance (against gravel throw
from tyres).
●
Suitable working temperature is
- 40ºC to 100ºC constant
working and upto 130º
C peaks.
●
PA is 7 to 8 times lighter than
metal.
●
Eliminates rusting problem, gives
much lower leakage.
●
Rust particles are not generated
(like in metal tubes) and thus
protects valves etc.
