The Difference Is in the Details

We believe that quality is in the details. Every component in our seal kit is a testament to our commitment to excellence. We use only premium-grade materials, carefully selected for their ability to withstand the extreme conditions of hydraulic systems.

  • High-Performance Materials: Our seals are crafted from materials like Nitrile Butadiene Rubber (NBR), valued for its oil and fuel resistance; and Polytetrafluoroethylene (PTFE), which offers exceptional low-friction properties.
  • Precision Engineering: We don't rely on generic parts. Each seal is precision-engineered to meet or exceed the original manufacturer’s specifications. This guarantees a perfect seal and prevents leaks, ensuring your Toku breaker operates with full force.
  • Rigorous Quality Control: Every batch of our Toku hydraulic breaker parts undergoes strict quality checks. This ensures that when you install our kit, you can trust in its performance and durability.

Our Manufacturing Excellence

Our manufacturing process is designed for one purpose: to deliver the most reliable hydraulic breaker seal kits on the market. From the sourcing of raw materials to the final packaging, every step is controlled to ensure a top-quality product.

Precision Material Weighing

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

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

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.

Seals Rigorous Quality Inspection

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.

  • Standard Export Packaging – Each seal kit is carefully packed in moisture-proof and dust-proof bags, ensuring seals remain clean and undamaged during storage and transportation.
  • Layered Protection – Kits are placed in sturdy cartons, and for bulk shipments, cartons are further reinforced with pallets and stretch film to minimize impact during handling and transit.
  • Customization Options – We provide OEM/ODM packaging services, including branded boxes, barcodes, and special instructions, helping partners strengthen their brand presence in local markets.
  • Extra Protection – For bulk shipments, cartons and pallets are reinforced to reduce the risk of damage in transit.

Order Processing & Lead Time

  • Standard Seal Kits – For large quantity orders, lead time is usually 7–10 working days, as each kit requires precise matching of every seal, followed by labeling and packaging.
  • Custom Seal Kits – For tailored requirements or non-standard models, production and assembly typically take 15–30 days, especially if new tooling or mold development is required.
  • Sample Orders – Small batch or sample kits can often be prepared faster, subject to stock availability.

Delivery Options

  • Air Freight for urgent orders
  • Sea Freight for bulk shipments
  • Courier Express (DHL, FedEx, UPS) for small packages and samples
