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.
Hydraulic breakers are among the most powerful attachments in mining, construction, and demolition, and Atlas Copco hammers are trusted worldwide for their impact strength and reliability. To maintain peak performance, a high-quality Hydraulic Breaker Seal Kit is essential. These seals play a vital role in keeping hydraulic fluid contained, protecting against dust and debris, and ensuring consistent power output during heavy-duty operations
Quality Manufacturing Process
Every seal kit is produced under strict quality control procedures:
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 process guarantees reliable sealing even under the harshest operating conditions.

Quality Manufacturing Process
Every seal kit is produced under strict quality control procedures:
- Certified Materials – Tested for hardness, elasticity, and temperature resistance.
- CNC Machining Precision – Accurate dimensions for proper OEM fit.
- Rigorous Performance Testing – Pressure, wear, and leak simulations.
- Final Quality Inspection – Ensures every kit meets Atlas Copco specifications.
This process guarantees reliable sealing even under the harshest operating conditions.
Seal Placement
In hydraulic breakers, critical seals are strategically positioned around the piston, cylinder, and valve system to ensure:
- 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.
Clear structural diagrams enable users to better understand how the seal kit integrates with the breaker's internal systems and why correct replacement is critical to performance.
Material Overview for Seal Kits
The performance of a seal kit depends heavily on the materials used. We select compounds based on durability, elasticity, and resistance to hydraulic oil and heat:
Nitrile Rubber Buna(NBR, BUNA-N)
Temperature Range:-30 to 125 ℃
Hardness:60-90 Shore A
Color: Black
Use: Oil & Water Resistance Situation Advantage: Excellent oil resistance, performance and stability, widely used, cheaper
Fluororubber(FKM,FPM)
Temperature Range:-20 to 250℃
Hardness:70-90 Shore A
Color: Black/Brown/Green
Use: Oil & Chemical Resistance Situation
Advantage: Wear resistance, acid and alkali resistance, high temperature resistance situation
