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.
Rammer breakers are known globally for their efficiency and impact power, but constant exposure to high pressure and vibration makes sealing components one of the most critical parts of the system. The Rammer Hydraulic Breakers Seal Kit provides a complete sealing solution to maintain hydraulic integrity, reduce maintenance downtime, and extend the lifespan of the breaker. With this kit, operators can rely on consistent performance even in the most demanding construction, demolition, or mining environments.
OEM Fitment & Cross Reference Seals
The Rammer Seal Kit covers a wide range of breaker models, including:
| Part Numbers | |||||||
|---|---|---|---|---|---|---|---|
| E63 | E64 | E65 | E66 | E66N | E68 | S18 | S21 |

For quick and accurate identification, we also provide cross reference seals support. By matching OEM part numbers or seal kit codes, customers can easily confirm the correct replacement kit, ensuring a perfect fit and reliable sealing for their breaker.
Engineering Standards & Quality Control
Our Hydraulic Breaker Seal Kits are produced with OEM-level precision and go through a strict quality assurance 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.
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.
Material Overview for Seal Kits
Our seal kits are manufactured from premium elastomers, polyurethane, and PTFE specially formulated to resist hydraulic oil, extreme heat, and heavy impacts. Unlike standard seals that wear quickly, these components are engineered to maintain elasticity and precision fit throughout prolonged use. Every kit is subject to strict quality inspections to ensure compliance with OEM-level performance standards.
