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.
The hydraulic seal kit is essential for the proper operation of Hanwoo hydraulic breakers. Its primary function is to prevent internal hydraulic fluid leakage while blocking external contaminants from entering the breaker system. A reliable seal kit ensures stable pressure, smooth piston movement, and consistent impact force. Without effective sealing, the breaker may suffer from reduced efficiency, overheating, or premature wear of key components.
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 summary: Every kit is produced under controlled standards to meet or exceed OEM sealing performance, giving operators peace of mind in heavy-duty applications.
Advanced Materials and Design
Our Hanwoo seal kits are crafted from premium elastomers and polymers such as NBR, PU, and Viton (FKM). These materials are carefully selected for their ability to handle:
- High hydraulic pressure without deformation.
- Extreme working temperatures found in long demolition cycles.
- Resistance to abrasion and chemicals present in construction and mining sites.
Each seal is manufactured with precise tolerances, ensuring perfect compatibility with Hanwoo breakers. The design emphasizes not only durability but also easy installation, minimizing machine downtime.
OEM Compatibility
The Hanwoo Hydraulic Breaker Seal Kit is specifically designed to fit a wide range of Hanwoo breakers, ensuring reliable replacement and long-lasting sealing effect. Compatible models include:
- Compact Series: HB05, HB08, HB10 – commonly used in small construction and municipal works.
- Medium Series: HB15, HB20, HB25 – widely applied in excavation, road construction, and foundation projects.
- Heavy-Duty Series: HB30, HB35, HB40, HB50 – suitable for mining, quarrying, and large-scale demolition.

Quality Control and Reliability
Before shipment, every seal kit passes through a series of inspections:
- Dimensional Accuracy Tests to ensure proper fitting.
- Hydraulic Pressure Endurance Tests to simulate real working conditions.
- Material Hardness & Elasticity Checks to guarantee long service life.
This strict quality assurance process ensures that our Hanwoo seal kits maintain their performance even under continuous high-impact use.
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
Hanwoo seal kits are produced from high-grade elastomers. These materials are chosen for their superior resistance to heat, hydraulic pressure, and abrasive working conditions. Advanced molding techniques and strict dimensional controls guarantee an exact fit, while post-curing treatments enhance flexibility and durability under heavy impact cycles.
