This cooling system inlet pipe gasket is a sealing component for the engine cooling system of FAW Jiefang J7 heavy truck. It is installed at the flange joint of the cooling inlet pipe to prevent coolant leakage. Made of high-quality heat-resistant composite material, it maintains stable sealing performance under high temperature and pressure during long-haul heavy-load operation. Each gasket undergoes dimensional inspection and liquid tightness test before delivery. It solves the failure of coolant leakage caused by gasket aging and damage, serving as an essential replacement spare part for cooling system maintenance.
