C.PRO tubes are produced with a very innovative bio-sourced polymer named polyamide 1012 (PA1012). Developed to overcome PA12 and PA11 chronic shortage, C.PRO tubes comply fully with ISO 7628-2010 standard and fulfill the requirements of DIN 73378 and 74324. Widely used in the automotive sector since years, C.PRO tubes show similar characteristics to PA12 or PA11 with excellent resistance to impact at -70°C and very good behavior above 125°C.
