One New Aftermarket Replacement Ring Seal for Caterpillar (Cat) Wheeled Excavators
This aftermarket replacement ring seal (part number 1183120, also referenced as 118-3120 and CA1183120) is a hydraulic rod seal used in the blade cylinder of Caterpillar wheeled excavators. The rod seal prevents pressurized hydraulic fluid within the cylinder from leaking, helping maintain system pressure and equipment performance. Worn or damaged rod seals can lead to hydraulic fluid loss, reduced digging and grading force, and potential system failure.
