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.
The Atlas Copco Hydraulic Breaker Seal Kit is specifically engineered to deliver superior sealing performance and long-lasting durability for hydraulic hammers operating in the most demanding applications, including mining, construction, quarrying, and demolition. Atlas Copco breakers are known worldwide for their power, reliability, and efficiency, but their hydraulic systems are continuously exposed to extreme pressure, high-frequency vibration, dust, and abrasive debris.
Without a quality seal kit replacement, problems such as oil leakage, power loss, reduced impact energy, and accelerated component wear can occur, resulting in costly downtime and frequent maintenance. Our hydraulic hammer seal kits for Atlas Copco are manufactured to meet strict OEM specifications, ensuring a precise fit, restoring the breaker’s original impact force, enhancing overall reliability, and extending service life while lowering maintenance costs.
Manufacturing Process
Each seal kit undergoes a strict production and inspection process:
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.

Quality Control & Manufacturing Standards
Every seal kit goes through a rigorous production process:
- Certified Material Sourcing – ensures consistent quality.
- CNC Precision Manufacturing – guarantees exact dimensional accuracy.
- Pressure & Wear Testing – simulates real breaker operating conditions.
- Final Quality Inspection – ensures every kit meets OEM standards before shipping.
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.
