Fluorocarbon-Lined Silicone EGR Sensor Hose |
|
 EGR Sensor hoses are used on diesel truck engines to deliver pressurized, cooled exhaust from the EGR crossover pipe to the EGR sensor. The temperature of the exhaust gasses is approximately 232ºC (500ºF). The purpose of the hose is to isolate the sensor from the exhaust heat by dead heading exhaust air allowing it to cool and preventing the thermal conductivity of steel tubing from heating the sensor. |
