NBR EPDM 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.

Boman NBR EPDM Bonded Seals Advantages:

1. Solid Fixing: Bonded seals are intended to give a dependable and durable seal. They comprise of a metal washer with an elastic fixing component clung to it. The elastic component gives brilliant fixing properties, guaranteeing a tight seal between mating surfaces.

2. Protection from Spillage: Bonded seals are viable in forestalling spillage of liquids or gases. The elastic fixing component makes a tight seal that opposes pressure and forestalls releases, significantly under high-tension circumstances.

3. Easy Installation: Bonded seals are easy to install and require minimal preparation. They can be quickly and securely fitted into the sealing groove, reducing assembly time and improving productivity.

4. Wide Compatibility: Bonded seals are available in a variety of materials, including Nitrile (NBR), Viton (FKM), and EPDM, among others. This allows for compatibility with different fluids, chemicals, and temperature ranges, making them suitable for a wide range of applications.

5. Resistance to Fluids and Chemicals: Bonded seals exhibit excellent resistance to a variety of fluids, including oils, fuels, hydraulic fluids, water, and gases. They also offer resistance to a wide range of chemicals, ensuring reliable sealing performance in diverse environments.
