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.
Daenong hydraulic breakers are trusted in construction, quarrying, mining, and demolition for their powerful impact energy and reliability. However, the harsh operating conditions—constant vibration, hydraulic pressure surges, dust, and debris—place extreme stress on sealing systems. Without proper sealing, oil leaks, energy loss, and premature component wear can cause costly downtime.Our Daenong Hydraulic Breaker Seal Kits are specifically engineered to meet OEM specifications, providing precise sealing, maximum oil retention, and extended component life. Whether for routine maintenance or complete breaker overhaul, these kits restore your equipment’s original power and efficiency, ensuring your breaker continues to perform in the most demanding environments.
Manufacturing Pross
Our production process ensures each seal kit delivers maximum reliability:
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.
This strict process ensures every Daenong seal kit delivers dependable performance and OEM-level fit.

Applications
- Construction: Foundation work, trenching, road projects
- Mining & Quarrying: Rock breaking, aggregate processing
- Demolition: Breaking reinforced concrete, structure removal
- Earthmoving: General excavation and land clearing
Seal Placement
Daenong breakers rely on sealing systems in multiple critical areas:
- Piston & Cylinder Zones – To maintain hydraulic pressure and impact power
- Valve Systems – Ensuring efficient oil flow and operational stability
- Tool Bushings & Tie Rod Areas – Preventing contamination and wear
- Front Head & Back Head Seals – Protecting against oil leakage and dust intrusion
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 Quality & Reliability
Our seal kits are manufactured using premium-grade sealing compounds such as NBR, PU, PTFE, and FKM, chosen for their proven resistance to:
- Hydraulic oils and fluids
- High operating temperatures
- Continuous vibration and shock loads
- Dust, dirt, and abrasive debris
Summary: These advanced materials ensure long-term durability and consistent sealing performance, even in the toughest working environments.
