GB Hydraulic breaker seal kits play a critical role in maintaining the performance and reliability of hydraulic breakers. This kit provides a complete set of seals, O-rings, and wear-resistant components that prevent oil leakage and contamination. Proper sealing ensures smooth piston movement, consistent impact force, and efficient energy transfer during demolition, trenching, or mining operations.
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.
Summary: The production process guarantees that every seal kit component meets high performance standards, minimizing downtime and maintenance costs.

Applications
- Demolition Projects: Ensures reliable breaker operation for concrete and asphalt.
- Trenching and Excavation: Maintains performance in consistent high-impact cycles.
- Mining and Quarrying: Protects the breaker from contamination and wear in harsh environments.
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.
