Kinton Seals is trusted by professionals worldwide for providing high-quality seal kits for excavators, dozers, loaders, and other heavy machinery, ensuring reliable performance and long-lasting durability.
Furukawa hydraulic breakers are well-known for their high impact power, efficiency, and durability, making them a trusted choice for construction, quarrying, tunneling, and mining projects. However, to maintain optimal performance, the hydraulic sealing system must always be in top condition.
Our Furukawa Seal Kits are precision-engineered to match OEM specifications, ensuring a perfect fit and reliable sealing. By replacing worn seals in time, you prevent issues such as hydraulic oil leakage, power loss, excessive wear, and costly equipment downtime. With our kits, your breaker regains its original striking force, extending both productivity and equipment lifespan.
Quality Manufacturing Process
Each seal kit undergoes strict quality checks to ensure long-lasting performance:
Precision Material Weighing
Each raw material block is carefully weighed with high-accuracy equipment before processing. This ensures that every seal ring starts with the exact material volume required for its specific size and application, preventing inconsistencies in density or performance.
Mold Preparation & Material Placement
After weighing, the prepared material is positioned onto the appropriate mold. Our workshop is equipped with a wide variety of molds to match different seal ring diameters and cross-sections. The correct mold selection guarantees precise shaping, while careful placement avoids defects such as uneven thickness.
High-Pressure Compression Molding
The molds are then set under specialized compression machines, where controlled pressure and temperature are applied. This process allows the material to be fully formed into a durable seal with consistent hardness and elasticity. Strict monitoring ensures every batch meets dimensional accuracy and structural integrity.
Rigorous Quality Inspection
Each batch of seals undergoes rigorous testing after molding. Technicians check for dimensional accuracy, surface smoothness, hardness, and sealing resilience. Any defective products are filtered out, ensuring that only seals with stable performance and long service life proceed to packaging.
In conclusion, choosing our Furukawa Hydraulic Breaker Seal Kit helps operators achieve reduced downtime, lower maintenance costs, and extended equipment life, making it the ideal replacement solution for any heavy-duty Furukawa breaker.

Applications
Our Furukawa Seal Kits are engineered for diverse working environments, including:
- Urban Demolition & Recycling – Breaking reinforced concrete and structures
- Mining & Quarrying – Crushing rock and heavy ore under extreme loads
- Infrastructure Projects – Road, bridge, and tunnel construction
- General Construction – Heavy-duty excavation and foundation works
Whether in harsh outdoor sites or continuous industrial use, these kits guarantee maximum sealing reliability and breaker protection.
Seal Placement
Seals are strategically installed in piston, cylinder, valve, and tie rod areas of breakers. They work together to:
- Prevents leakage of hydraulic oil under high pressure.
- Protecting internal components from dust, water, and abrasive particles.
- Provides smooth piston and connecting rod movement and consistent impact force.
- Reduces wear on metal components by maintaining proper lubrication.
Seals are strategically placed in the piston, cylinder, tie rods, and valve areas, ensuring full hydraulic protection and preventing premature wear of critical components.
