Soosan Hydraulic Breaker Seal Kit: A Core Component for Peak Performance
In the demanding world of demolition and excavation, your Soosan hydraulic breaker is only as reliable as its internal components. A failing seal can quickly compromise your equipment, leading to pressure loss, oil leaks, and costly operational delays. Our Soosan Hydraulic Breakers Seal Kit is engineered to provide a robust and durable solution, restoring your breaker's power and efficiency.
This seal kit is perfectly compatible with a variety of Soosan models, including the widely used SB series and SQ series hydraulic hammers. It’s an essential maintenance item for models such as the SB70, SB81, and SQ100. Our comprehensive kit includes all the necessary seals, O-rings, and wipers for a complete and thorough overhaul.

Precision Engineering for Soosan Equipment
Our commitment to quality begins long before the kit is assembled. We follow a rigorous process to ensure every seal meets our high standards:

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.

The Assurance of Quality Materials
A seal is only as good as the material it’s made from. We use only premium-grade materials selected for their specific properties, guaranteeing the durability and long-term performance of our Soosan seal kits.

Why Our Seal Kit is the Smart Choice
Choosing the right seal kit is a critical decision that impacts your machine’s lifespan and performance. Here’s what sets our Soosan seal kits apart:
- Engineered for Durability: Our seals are crafted from high-grade materials like Nitrile Butadiene Rubber (NBR), and Polytetrafluoroethylene (PTFE). These materials are chosen for their superior resistance to wear, high temperatures, and chemical degradation.
- Precision Manufacturing: Every seal is manufactured to exacting specifications, ensuring a flawless, leak-proof fit. This precision is vital for maintaining the high internal pressure required for effective breaking.
- Comprehensive Solution: We save you the hassle of searching for individual parts. Each kit is meticulously assembled with every component you need for a complete rebuild, getting your equipment back to work faster.
Invest in Performance and Longevity
A quality seal kit is more than just a repair part—it's an investment in the longevity and reliable operation of your equipment. By proactively replacing worn seals with a high-quality kit, you can significantly reduce downtime, prevent costly internal damage, and ensure your Soosan hydraulic breaker operates at its peak for years to come.
