Product Description
5408704611501 Differential Pressure Sampling Pipe is a small signal hose matched for JAC QCQ25 exhaust aftertreatment system. It connects the DPF body and differential pressure sensor, transmitting pressure signals from upstream and downstream of particulate filter to calculate soot accumulation level inside the filter. This aftermarket replacement pipe resolves emission fault alerts, incorrect soot load reading and regeneration failure caused by pipe blockage, cracking and joint air leakage of old sampling tubes. Accurate pressure feedback ensures normal DPF regeneration logic and helps light trucks comply with emission requirements for daily delivery operation.
Product Advantages Special heat-resistant and anti-sulfur rubber material adapts to high exhaust ambient temperature. Small-bore smooth inner channel avoids soot deposition and clogging. Soft flexible structure absorbs engine and exhaust pipe vibration to prevent fracture. Every sampling pipe undergoes air tightness test before shipment, molded shape and connector size match original layout for direct fitting.

FAQ
Q1: What fault will occur if this sampling pipe is blocked by soot?
A1: The sensor receives wrong pressure value, triggering false DPF full alarm and failed active regeneration.
Q2: Why check both sampling lines at the same time during replacement?
A2: Both upstream and downstream pipes work as a pair; damage on either one affects pressure difference calculation.
Q3: What installation requirement should be followed for this sampling pipe?
A3: Arrange the pipe with gentle slope and avoid low sagging sections where condensate and soot gather easily.
