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.
Volvo excavators are widely recognized for their efficiency and advanced hydraulic systems. To keep these machines running at peak performance, hydraulic seal kits play a critical role. Our Volvo Excavator Hydraulic Seal Kits are engineered with premium-grade materials and precise dimensions to guarantee compatibility, excellent sealing, and resistance to wear under heavy-duty working conditions.
These kits are suitable for boom cylinders, arm cylinders, bucket cylinders, and other key hydraulic components, helping operators reduce downtime and avoid costly repairs caused by hydraulic fluid leaks.
Manufacturing Process & Quality Control
Our Volvo hydraulic seal kits are produced under strict process 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.
Seal Kit Composition
Our excavator seal kits are composed of multiple sealing elements that work together to ensure performance:
- Piston Seals – Maintain fluid separation between high- and low-pressure zones.
- Rod Seals – Prevent fluid leakage during piston rod movement.
- Dust Seals / Wipers – Protect cylinders from contaminants such as dust, mud, and water.
- O-Rings & Backup Rings – Ensure precise fitting and eliminate micro-leaks under pressure.
- Wear Rings – Reduce metal-to-metal contact and improve cylinder alignment.
This comprehensive structure ensures that Volvo machines maintain peak hydraulic efficiency across diverse working conditions
OEM Compatibility and Fitment
Our seal kits are available for a wide range of Volvo excavator models, including:
- EC210, EC240, EC290, EC360, EC380, EC460, EC480
- EW140, EW160, EW180, EW210 wheeled excavators
