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 Arrowhead Hydraulic Hammer Seal Kit is an indispensable solution for ensuring long-term reliability and performance of your breaker. Hydraulic hammers operate under severe working conditions—high pressure, repetitive impacts, dust, and debris. Without proper sealing, hydraulic oil leaks and reduced impact power can quickly cause costly downtime.
Our seal kits are specifically engineered to provide leak-proof protection and maintain consistent breaker performance. With precision fitment for Arrowhead models, they allow contractors and operators to maximize productivity while minimizing unplanned repairs.
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
To guarantee performance, our Arrowhead breaker seal kits are produced under strict standards:
- Material Certification – Only tested and approved compounds are used.
- CNC Machining Precision – Ensures exact dimensional accuracy for OEM fit.
- Pressure & Wear Testing – Simulated to replicate real-world hammer usage.
- Final Inspection – Every kit is checked before packaging and shipping.
This ensures each kit meets or exceeds OEM requirements.
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.
