The 690786-6 is a seal, available as an O-ring, that is commonly utilized in the nuclear industry as a pressure vessel seal. This seal is designed to provide optimal efficiency and safety for a variety of nuclear applications.

The 690786-6 seal is typically made of a special elastomer, such as HNBR, silicone, polyurethane, or Viton. This material provides greater strength, flexibility, and resilience than standard elastomers. It also has a very low outgassing rate, making it ideal for nuclear applications.

The 690786-6 O-ring is generally used in pressure vessels, such as reactors, pipes, and storage tanks. It is ideal for these applications because it is extremely resistant to chemicals, corrosion, and other extreme temperatures. It is also able to withstand high pressures and vibration, making it a great choice for sealing nuclear applications.

The seal itself is a circular ring that is able to fit within the confines of a pressure vessel. It is designed to provide a watertight seal between the vessel walls. The circular shape allows it to easily conform to the walls of the pressure vessel, providing a secure and reliable seal.

When the 690786-6 O-ring is installed, it is inserted into the pressure vessel’s wall grooves. This creates a tight seal between the vessel’s walls and the O-ring itself. This seal ensures that no gases, liquids, or other substances can escape from the pressure vessel. Additionally, it prevents any unwanted substances from entering the vessel.

The 690786-6 O-ring works on the premise of elastomeric deformation. As the pressure within the vessel increases, the metal walls of the vessel push on the O-ring. This causes the O-ring to deform, providing a tighter seal between the vessel walls and the O-ring itself. This ensures that no gases or liquids are able to escape through the seal.

The 690786-6 O-ring is also designed to be highly durable and reliable. It has been tested to withstand high temperatures, extreme conditions, and constant vibration. This makes it a great choice for nuclear applications, as it will provide a long-lasting and effective seal.

In summary, the 690786-6 seal is a reliable sealing solution for nuclear applications. It is made from high-quality elastomers, which provide greater strength, flexibility, and resilience than standard elastomers. Additionally, it is highly durable and can withstand high pressures, vibration, and extreme conditions. As such, it is an ideal choice for providing a secure and reliable seal between pressure vessels and their walls.
