This intercooler suction pipe gasket is a sealing component of the engine air intake system for FAW Jiefang J7 heavy truck. It is installed between the intercooler suction pipe and connecting flange, used to seal the joint surface and prevent pressurized intake air leakage. Made of high-quality heat-resistant composite material, it maintains stable sealing performance under high temperature and boost pressure in long-haul heavy-load working conditions. Each gasket undergoes dimensional inspection and sealing test before delivery. It solves faults such as insufficient engine power caused by air leakage at the intercooler pipeline joint, serving as an essential replacement spare part for intake system maintenance.
