Non Self-Centering Bonded Seal

Bonded seal called Dowty seal or a sealing washer, is a specialized type of sealing device used to create a reliable and leak-proof seal in high-pressure applications. It combines the properties of a metal washer and a rubber seal, providing an effective sealing solution for threaded connections.
They consists of a metal washer with a rubber sealing ring bonded to its inner diameter. The metal washer provides structural support and helps distribute the compressive load evenly, while the rubber seal ensures a tight and secure seal against the mating surfaces.
Also are commonly used in hydraulic systems, automotive applications, plumbing connections, and other high-pressure sealing applications. They offer a reliable, easy-to-install, and cost-effective sealing solution, making them a preferred choice in industries that require effective sealing under challenging conditions.

1.Reliable Sealing Performance: Bonded seals offer a reliable and durable sealing solution, ensuring a tight and leak-proof seal in high-pressure environments. The combination of the metal washer and the rubber seal provides effective sealing against fluid leakage.

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.Versatility: Bonded seals are available in various sizes and materials to accommodate different applications and thread sizes. They can be used with both metric and imperial threads and can be customized to meet specific requirements.

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.Reusability: Bonded seals can often be reused, providing cost savings and convenience. When disassembling connections, the bonded seal can be removed, inspected, and reinstalled if it is in good condition.

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.

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.Industrial Equipment and Machinery: Bonded seals are used in various industrial equipment and machinery where reliable sealing is required under high-pressure conditions. They find applications in pumps, compressors, valves, and hydraulic systems across industries like manufacturing, mining, construction, and more.

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.Process Industries: Bonded seals are used in process industries, including chemical plants, oil refineries, and food processing facilities. They provide a reliable sealing solution in threaded connections, ensuring leak-free operation and preventing contamination.
