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.
EDT hydraulic breakers are widely used in road construction, demolition, quarrying, and heavy excavation projects, where equipment must endure continuous shock loads and high-pressure hydraulic flow. Over time, seals deteriorate due to constant vibration, heat buildup, and contamination by dust and abrasive particles. The EDT Hydraulic Breaker Seal Kit is an essential maintenance solution that restores breaker performance, prevents hydraulic oil leakage, and keeps your hammer operating at peak efficiency. By ensuring tight sealing, the kit reduces energy loss, maintains impact power, and helps lower unexpected repair costs and downtime.
Quality Manufacturing Process
Our EDT breaker seal kits are produced under strict quality control:
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.
Every EDT Hydraulic Breaker Seal Kit is designed to provide stable sealing, improved efficiency, and maximum reliability, even under the toughest jobsite conditions.

Applications
- Construction Projects – Roadworks, foundations, and trenching.
- Mining & Quarrying – Hard rock breaking and aggregate extraction.
- Demolition – Concrete and reinforced structure removal.
- Heavy Earthmoving – High-power excavation and land development.
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.
