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.
A hydraulic breaker depends on a reliable sealing system to deliver consistent impact energy. The Konan seal kit serves as a barrier against hydraulic oil leaks while protecting the piston, cylinder, and other internal components from dust, dirt, and water intrusion. By maintaining stable hydraulic pressure, it ensures the breaker operates smoothly, maximizing productivity and reducing costly downtime.
Quality Manufacturing Process
The Hydraulic Breaker Seal Kit is manufactured using advanced molding and finishing processes, ensuring precise dimensions and long-lasting performance. Key production steps include:
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.
Through these steps, each Konan Hydraulic Breaker Seal Kit achieves OEM-level performance, guaranteeing dependable sealing even under extreme working conditions.
OEM Compatibility and Cross Reference Seals
The Konan Hydraulic Breaker Seal Kit is designed to fit a wide range of breaker models, from compact units used in city construction to large breakers for heavy-duty mining. Examples include:
- Small Series: Commonly applied in municipal and light demolition work.
- Medium Series: Widely used in trenching, road building, and foundation projects.
- Heavy-Duty Series: Built for mining, quarrying, and large-scale demolition.

Applications
- Construction and Demolition: Maintains hydraulic stability during repetitive hammering.
- Quarrying and Mining: Withstands abrasive dust and debris in tough environments.
- Infrastructure Projects: Provides reliable sealing for trenching, foundation, and roadwork applications.
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.
