JCB Excavator seal kits

Browse aftermarket replacement hydraulic seal kits for JCB excavators, including boom, arm/dipper, bucket, rotary-coupling and other hydraulic applications. Fujis Seal organizes this collection to help identify the correct kit by JCB machine model, OEM/reference part number, hydraulic component and available serial or dimensional information.

How to Identify the Correct JCB Excavator Seal Kit

• Machine model: confirm the complete JS, JZ or other JCB excavator model.
• Serial number: useful when one model family uses more than one component revision.
• Component position: boom, arm/dipper, bucket, rotary coupling, valve or another hydraulic assembly.
• Part number: match every digit, slash and suffix from the JCB reference.
• Rod/bore dimensions: use as a secondary check when listed.

A rotary-coupling seal kit and a cylinder seal kit service different assemblies and should not be treated as interchangeable.
