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.
A Chicago Pneumatic Hydraulic Breaker Seal Kit is more than just a set of replacement parts—it is the key to keeping your breaker running at peak efficiency. Hydraulic breakers are exposed to intense impact energy, continuous vibration, high pressure, and abrasive dust, all of which put enormous stress on the hydraulic system. Without effective sealing, equipment may suffer from hydraulic oil leakage, power loss, increased fuel consumption, and costly unscheduled downtime.
Our seal kits are precision-engineered to meet Chicago Pneumatic OEM specifications, ensuring a perfect fit and restored factory-level performance. By protecting vital hydraulic components, they help extend breaker lifespan, reduce total operating costs, and improve overall productivity.
Quality Manufacturing Process
Every Chicago Pneumatic seal kit is developed through:
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.

Typical Worksite Applications
- Mining & Quarry Operations – Breaking rocks and ore efficiently.
- Road & Civil Construction – Trenching, tunneling, and site preparation.
- Demolition & Recycling – Concrete structure dismantling.
- Utility Work – Underground pipeline and foundation projects.
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.
