FKM Stainless Steel Bonded Seal

Stainless steel bonded seals, also known as Dowty seals or bonded washers, are specialized sealing devices widely used in various industries and applications to provide effective and reliable sealing against fluid leakage. These seals consist of a metal washer, typically made of stainless steel, bonded with an elastomeric sealing ring, which is usually made of rubber or other elastomers. The combination of these two materials creates a robust and efficient sealing solution with unique advantages.

Boman Stainless Steel Bonded Seals Advantages:

1. Chemical Compatibility: Stainless steel bonded seals are resistant to a wide range of chemicals and fluids, including oils, fuels, hydraulic fluids, and various industrial chemicals. This chemical resistance ensures reliable sealing in diverse applications.

2. High Pressure and Temperature Resistance: Bonded seals are specifically designed to withstand high pressures and temperatures. They can be used in applications where conventional sealing methods may fail due to the extreme operating conditions.

3. Anti-Extrusion Properties: The metal washer in stainless steel bonded seals acts as an anti-extrusion device, preventing the elastomeric sealing ring from extruding under high pressure, enhancing the seal's longevity.

4. Corrosion Resistance: Stainless steel is highly resistant to corrosion and rust. It contains chromium, which forms a passive oxide layer on the surface, protecting it from corrosive elements such as moisture, chemicals, and atmospheric conditions. This makes stainless steel ideal for applications in harsh environments or where exposure to corrosive substances is common.

5. High Strength and Durability: Stainless steel bonded seals are known for their high strength and durability. They can withstand high pressures and temperatures without deforming or losing their sealing properties, ensuring long-lasting and reliable performance.

6. Wide Temperature Range: Stainless steel bonded seals can operate effectively across a wide temperature range, from low temperatures to high temperatures. They can maintain their sealing integrity even in extreme temperature conditions, making them suitable for a variety of applications.

7. Heat and Fire Resistance: Stainless steel has excellent heat resistance properties, allowing it to withstand high temperatures without deformation or loss of strength. It is commonly used in applications that involve heat, such as industrial ovens, cookware, and exhaust systems. Stainless steel also has a high melting point, making it resistant to fire and contributing to fire safety in buildings and transportation.


In summary, stainless steel bonded seal offers corrosion resistance, durability, strength, hygienic properties, aesthetic appeal, heat resistance, and recyclability.
