Hitachi Excavator seal kits
Explore aftermarket replacement hydraulic seal kits for Hitachi and selected Fiat-Hitachi excavators. This collection covers boom, arm/stick, bucket, swing-cylinder and center-joint applications across EX, ZX and related machine families. Fujis Seal organizes listings for research by machine model, OEM/reference part number, hydraulic component, serial range and available rod/bore dimensions.
How to Match a Hitachi Excavator Seal Kit
A model number alone does not always identify the correct kit. EX and ZX machines can use different cylinders or sealing arrangements according to serial range, regional specification and component configuration.
- Brand/application: confirm Hitachi or Fiat-Hitachi.
- Model and suffix: record the full designation, including LC, H, K, LCH or other suffixes.
- Component: identify boom, arm/stick, bucket, swing cylinder or center joint.
- OEM/reference number: match the complete number where available.
- Rod/bore dimensions: use as a secondary check.
Center-joint kits and cylinder kits service different components and are not interchangeable.

Are these genuine Hitachi parts?
Unless a product listing expressly states otherwise, products are aftermarket replacement seal kits supplied by Fujis Seal. Hitachi and Fiat-Hitachi names and references are used for compatibility and product identification only.
