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.
Fine hydraulic breakers are widely used in demolition, road construction, mining, and quarry operations, where they are constantly exposed to dust, moisture, high pressure, and repeated impact loads. In such extreme environments, maintaining the integrity of the hydraulic system is crucial. The seal kit is one of the most essential components of a hydraulic breaker, as it prevents hydraulic oil leaks, reduces contamination, and ensures consistent pressure levels. A damaged or worn-out seal can quickly lead to power loss, excessive wear of internal components, and costly downtime.
Our Fine Hydraulic Breakers Seal Kits are engineered to deliver maximum sealing efficiency, durability, and reliability. With advanced materials and precision manufacturing, they provide OEM-equivalent performance and help operators maintain full breaker productivity with lower maintenance expenses.
Quality Manufacturing Process
Each Fine breaker seal kit is produced under strict manufacturing and quality control standards:
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
Our seal kits are specially developed for operators who work in:
- Demolition & Recycling – Breaking concrete and reinforced structures
- Mining & Quarrying – Crushing rocks and hard materials under extreme pressure
- Road & Bridge Construction – Removing old foundations and asphalt layers
- General Construction – Heavy-duty excavation and foundation work
Wherever maximum breaker efficiency is required, our Fine seal kits ensure optimal performance and long-lasting reliability.
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.
