Caterpillar 4N-1418 is a general‑use radiator inlet gasket for CAT cooling assemblies. It provides a 0.8 mm thick seal spread over a 102 mm by 102 mm footprint, making it suitable for a range of radiator inlet interfaces. Available constructions include rubber and cork, rubber and fiber, or all‑rubber variants to suit different sealing needs. This gasket’s primary role is to seal the radiator inlet joint, helping prevent coolant leaks in Caterpillar equipment.
