Komatsu
Browse aftermarket replacement seal kits for Komatsu hydraulic breakers, including JTHB-series breaker and hammer applications. Fujis Seal organizes this collection to help match the correct kit by breaker model, serial range, reference number and internal seal configuration.
How to Identify the Correct Komatsu Hydraulic Breaker Seal Kit
- Breaker model: confirm the complete JTHB model and revision.
- Serial number: important when a model has multiple internal versions.
- Reference number: match the complete kit or breaker reference where available.
- Photos/markings: use the breaker nameplate and old seal markings if the number is unclear.
Hydraulic breaker seal kits are different from excavator cylinder seal kits, so select the kit by the breaker itself rather than by the carrier machine alone.
Fitment Support from Fujis Seal
If the breaker version is unclear, contact Fujis Seal with the JTHB model, serial number, photos and any available part numbers.
Komatsu Hydraulic Breaker Seal Kit FAQs
Can one JTHB kit fit several breaker models?
Only when the individual listing confirms compatibility. Model and serial revisions can change the required seals.
Are these genuine Komatsu parts?
Unless a listing expressly states otherwise, products are aftermarket replacement seal kits supplied by Fujis Seal. Komatsu names and references are used for compatibility and identification only.
