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 trusted globally for their power, precision, and endurance. To maintain that performance, the hydraulic system depends on strong, durable seals to withstand high pressure, vibration, dust, and abrasive debris.
Over time, these seals wear out and may cause oil leaks, power loss, or overheating, resulting in costly downtime. Our Furukawa Seal Kits provide a direct replacement solution, manufactured with high-quality standards to ensure perfect compatibility, restored breaker impact power, and longer service intervals.
Quality Manufacturing Process
Each seal kit is produced through a strictly controlled manufacturing process, from material selection, precision cutting, to quality inspection. With the aid of advanced equipment and skilled craftsmanship, every kit achieves tight dimensional tolerances and consistent performance. The result is a product that not only meets but often exceeds OEM requirements, ensuring durability, reliability, and long-term cost savings for operators.

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.
Summary: With our Fine Hydraulic Breaker Seal Kits, you can count on long-lasting sealing reliability, optimized hydraulic performance, and reduced downtime, keeping your equipment ready for the toughest jobs.

Applications
- Construction Projects – Roadworks, foundations, and trenching.
- Mining & Quarrying – Hard rock breaking and aggregate extraction.
- Demolition – Concrete and reinforced structure removal.
- Heavy Earthmoving – High-power excavation and land development.
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.

Material Overview for Seal Kits
Our seal kits are produced with advanced sealing materials that balance flexibility, durability, and resistance to high pressure and heat. This ensures they can perform reliably under continuous operation and harsh conditions. By using carefully selected elastomers and polymers, our kits achieve stable sealing performance, minimal wear, and long service life, reducing the risk of unexpected breakdowns.
