Conti Excelsus from ContiTech (Louisville, KY) is an extremely flexible high-temperature hose with external reinforcement for truck and off-highway applications. Its flexibility comes from a special braid made of a plastic textile that is resistant to high temperatures and chemicals, allowing it to be used even in especially tight and complex installation situations. Depending on the particular finish, the hose can withstand temperatures of up to 482°F (250°C). This makes the hose suitable for use in extremely hot environments. It supplies the turbocharger with cooling water and lubricating oil, and is also used in its control system. In addition, the hose is also suitable for transporting air in, for instance, exhaust systems such as a diesel particulate filter or as a fuel return line.
