A Diesel Particulate Filter Pressure Sensor Hose is constructed from materials resistant to the fluid being conducted. The inner diameter of a hose refers to the measurement of the hollow hose's internal opening. It determines the flow rate and volume capacity of the hose. The outer diameter of a hose refers to the measurement of the hose's external circumference.Attributes:• Provide a smooth, uninterrupted flow of fluid, minimizing pressure drop• Inner diameter increases from 9.52mm to 12.7mmApplications:A Diesel Particulate Filter Pressure Sensor Hose is used to provide a conduit for the transmission of pressure data from the DPF (Diesel Particulate Filter Pressure Sensor) to the sensor. The sensor measures the pressure drop across the DPF, which helps determine the level of soot accumulation in the filter.
