View model pageGeneral guidance
In general, a gasket is a sealing component placed between two mating surfaces, such as metal housings or covers, to prevent leakage of fluids, air or dust while accommodating small surface irregularities. On heavy equipment, gaskets are used at joints throughout the machine, and the correct gasket must match the sealing surface and the operating conditions of its location.
Reference Caterpillar part number 2423489 when checking the item. Before ordering, compare the recorded catalog associations and their listed conditions with your machine's model and serial number, and confirm that this gasket is the one required for the specific joint being serviced.
