Kobelco Excavator seal kits

Browse aftermarket replacement hydraulic seal kits for Kobelco excavators, including boom, arm/stick, bucket and other cylinder applications across SK-series machines. Fujis Seal organizes this collection to help identify the correct kit by Kobelco machine model, OEM/reference part number, cylinder position, serial range and available rod/bore dimensions.

How to Identify the Correct Kobelco Excavator Seal Kit

Kobelco SK-series machines can use different cylinder versions across model suffixes and production ranges, so the exact model and reference number should be confirmed before ordering.

• Machine model: record the complete SK-series model and suffix.
• Serial number: useful when one model family uses multiple cylinder revisions.
• Cylinder position: boom, arm/stick, bucket or another hydraulic function.
• OEM/reference number: match the complete Kobelco reference, including letters and revision suffixes.
• Rod/bore dimensions: use as a secondary fitment check.

Similar dimensions do not always mean the same seal profile or groove design, so part-number matching remains the preferred method.

Fitment Support from Fujis Seal

Kobelco Excavator Seal Kit FAQs

Can one SK-series seal kit fit several models?

Only when the individual listing confirms compatibility. Model suffixes and cylinder revisions can change fitment.

Are these genuine Kobelco parts?

Unless a listing expressly states otherwise, products are aftermarket replacement seal kits supplied by Fujis Seal. Kobelco names and references are used for compatibility and product identification only.
