3E4297 O-Ring for Caterpillar Equipment

The 3E4297 O-ring is a sealing component for equipment manufactured by Caterpillar. It is used to seal fixed joints and selected moving connections where an elastomeric circular seal is required. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The available product data identifies the equipment brand as Caterpillar but does not specify individual machine models or series. Fitment should therefore be confirmed by matching the part number and the required seal dimensions with the service documentation for the equipment.
