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.

The Case Backhoe Loader Seal Kit is an essential replacement solution that restores the integrity of hydraulic cylinders in backhoe operations. Over time, seals are subject to wear due to pressure, temperature changes, and abrasive contaminants. A high-quality seal kit ensures that your loader’s boom, dipper, bucket, and stabilizer cylinders continue to operate smoothly without leakage or performance loss.
Material & Construction
Each seal kit is carefully engineered using premium PU, NBR, FKM, and PTFE materials, chosen for their resistance to oil, hydraulic fluids, and extreme working environments.
- Polyurethane (PU): Excellent elasticity and abrasion resistance, ideal for dynamic seals.
- Nitrile Rubber (NBR): Reliable sealing against hydraulic oil under high pressure.
- PTFE (Teflon): Low-friction performance to prevent sticking and overheating.
- FKM (Viton): Exceptional temperature and chemical resistance for heavy-duty use.
This combination ensures long-lasting protection and minimizes downtime in demanding construction sites.
Our Manufacturing Excellence
Our Case Backhoe Loader seal kits are produced under strict manufacturing standards. Every batch undergoes:

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.
Compatibility & OEM Fitment
Our Case Backhoe Loader Seal Kits are manufactured to strict OEM dimensions, ensuring perfect compatibility and easy installation. These kits are suitable for a wide range of Case backhoe models, including:
- Case 580 Super M / 580N / 580 Super N
