In general, a tee-union is a fitting with three connection ports arranged in a T shape, used to split or join a fluid line so that flow can branch or merge. In heavy equipment it is typically found in cooling and fluid circuits, where it connects hoses or tubes at a junction.
Order using the existing part number 0059702 for the tee-union. Because the catalog associations above are listed for specific Caterpillar models and assemblies, check the model, serial number and any qualifiers recorded for those occurrences against your machine before purchasing.
