⚠️ Buyer Fitment Disclaimer: CHECK WELL BEFORE PURCHASE! High-pressure hydraulic control systems look entirely identical from an outside glance but alter internal resistance ratings (Ohm curves), thread pitch parameters, and pin terminal alignments dynamically based on your equipment’s precise Chassis Serial Number Prefix. To ensure an absolute drop-in physical match, please verify your original parts book or cross-reference your serial sequence via the Official Cat Parts Store Portal prior to checking out. All sales of specialized hydraulic surplus assets are final—no returns or refunds are provided for ordering errors.
