Bonded Seals
Bonded Seals Overview
Bonded seals are integrated metal-rubber sealing components widely used in hydraulic, pneumatic and machinery industries. They combine stable metal support with elastic rubber sealing layer, featuring excellent leak resistance, high pressure resistance and easy installation. Ideal for static sealing applications to ensure long-term reliable operation of equipment.
KODA focuses on quality, consistency, and supply assurance, offering a wide range of imperial and metric adhesive seals to meet the needs of diverse industrial applications.

Advantages of Bonded Seals
Bonded seals deliver superior sealing performance with integrated metal and rubber structure. They boast high pressure resistance, excellent leak-proof effect and strong temperature adaptability. Featuring easy installation, stable fit and long service life, they effectively reduce fluid leakage, lower maintenance costs and ensure reliable static sealing in industrial machinery, hydraulic and automotive systems.
- High-Pressure Sealing: Provides a reliable seal for static connections exposed to high-pressure fluids.
- Leak Prevention: Ensures a secure barrier against fluid and gas leaks at bolted or threaded connections.
- Vibration Resistance: Maintains sealing integrity even under vibration, pulsation, and minor dynamic loads.
- Corrosion Resistance: Commonly offered with protective coatings for enhanced durability.
- Simplifies Installation: Eliminates the need for additional sealant, reducing assembly complexity.
- Cost-Effective: Provides long-term performance with minimal maintenance.

Materials
Bonded seals are manufactured using a carefully selected combination of materials to provide reliable sealing performance, durability, and compatibility with a wide range of fluids and operating environments. Elastomers provide the sealing function, while metal gaskets offer structural integrity. Coatings enhance corrosion resistance where applicable.
| Elastomer | Metal | Coating | MPa |
| NBR | Mild Steel | Zinc, CR (III) | 300 |
| FKM | Mild Steel | Zinc, CR (III) | 300 |
NBR (Nitrile) offers excellent resistance to oil and fuel, while FKM offers superior resistance to chemicals and high temperatures. Mild steel is a strong and cost-effective choice, paired with a corrosion-resistant coating.
