Great Seal Kit for Excavator Repair

This hydraulic cylinder seal kit was a great replacement for my Hitachi excavator. The seals fit properly and made the cylinder rebuild process straightforward. The components appear well made, and the hydraulic cylinder is operating smoothly after installation with no noticeable leaks. Everything arrived well packaged and in good condition. Very satisfied with the quality and fit.
