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.

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.Ease of Installation: Bonded seals are easy to install, requiring no special tools or complicated procedures. They are typically placed between the mating surfaces during assembly and provide a reliable seal when tightened.

5.Corrosion Resistance: Stainless steel bonded seals, being made of stainless steel, exhibit excellent corrosion resistance, making them suitable for applications exposed to harsh environments or corrosive fluids.

6.Resistance to Fluids and Chemicals: The rubber sealing ring in a bonded seal is resistant to various fluids, including oil, fuel, water, and hydraulic fluids. It also exhibits good chemical resistance, ensuring long-lasting sealing performance in diverse environments.

7.Long Service Life: The combination of durable stainless steel and high-quality elastomers ensures that stainless steel bonded seals have a long service life, reducing the need for frequent replacements and maintenance.

8.Reduced Leak Potential: Stainless steel bonded seals offer reliable sealing performance, minimizing the risk of fluid leakage and potential system failures.

Bonded Seal reliable sealing under high-pressure conditions is required. Here are some common applications::

1.Hydraulic Systems Seal: Bonded seals are extensively used in hydraulic systems, including pumps, valves, cylinders, and fittings. They provide a reliable seal between hydraulic components, ensuring leak-free operation and preventing fluid leakage under high-pressure conditions.

2.Automotive Industry Seal: Bonded seals are found in automotive applications, such as engines, transmissions, fuel systems, and braking systems. They are used in connections involving high-pressure fluids, ensuring secure and leak-free sealing in critical automotive components.

3.Plumbing and Pipelines Seal: Bonded seals are utilized in plumbing systems and pipelines to create a reliable seal in threaded connections. They are commonly used in water supply systems, oil and gas pipelines, and industrial plumbing applications.

4.Pneumatic Systems Seal: Bonded seals are suitable for sealing threaded connections in pneumatic systems. They provide an effective seal in applications such as air compressors, pneumatic cylinders, valves, and fittings.

5.Oil and Gas Industry: Stainless steel bonded seals are essential in the oil and gas sector for sealing connections in pipes, valves, pumps, and other equipment. They are used in both onshore and offshore applications, where they can withstand harsh environmental conditions and exposure to corrosive fluids.

6.Agriculture and Irrigation Systems Seal: Bonded seals are employed in agricultural machinery and irrigation systems, including pumps, valves, and fittings. They ensure leak-free sealing and reliable operation in agricultural equipment used for irrigation, fertilization, and other applications.

7.Marine and Offshore Applications: Bonded seals are suitable for sealing applications in marine and offshore environments. They are used in systems such as ship engines, hydraulic systems, offshore platforms, and underwater equipment where reliable sealing is critical.

8.Power Generation: In power generation equipment, such as steam turbines and gas turbines, stainless steel bonded seals are used to seal steam and cooling water connections.
