Pneumatic seal

What is a pneumatic seal?

A pneumatic seal is an essential component used to ensure tightness in pneumatic systems. They prevent the escape of pressurized air or gas, ensuring the efficiency and reliability of pneumatic systems. These seals are designed to withstand high pressures and rigorous operating conditions, while maintaining a perfect seal between the various parts of a pneumatic system.

Different profiles of pneumatic seals

Pneumatic seals come in a variety of profiles to meet specific needs:

• O-rings: Commonly used in pneumatic applications, these ring-shaped seals provide an effective seal and are easy to install.

• Lip seals: Designed with additional sealing lips, they offer enhanced protection against leakage and are ideal for high-pressure applications.

• U-seals: These seals have a U-shape that enables them to maintain a seal under pressure while allowing some axial or radial movement.

• Scraper seals: Used to prevent contamination of pneumatic systems by dust and debris, they scrape moving surfaces while maintaining a seal.

Special features of pneumatic seals

Pneumatic seals offer several key advantages that make them indispensable in a variety of applications:

• sealing under pressure: Designed to maintain an effective seal even under high pressures, they prevent air or gas leaks.

• Durability: Made from robust materials such as nitrile rubber (NBR), fluorocarbon (FKM) or polyurethane (PU), they resist wear, extreme temperatures and chemicals.

• Flexibility: Able to adapt to both axial and radial movements, these seals provide a continuous seal despite movement and vibration.

• Ease of installation: Available in different shapes and sizes, they are easy to install and replace, reducing downtime and maintenance costs.

How to choose the right part number?

To select the right pneumatic seal for your needs, several criteria need to be taken into account:

1. Specific application: Identify the specific requirements of your application, such as operating pressure, type of movement (axial, radial), and environmental conditions (temperature, chemical exposure).

2. Seal type: Choose between different types of pneumatic seals (O-rings, lip seals, U-rings, wipers) depending on the performance required. O-rings are commonly used for their simplicity, while lip and U-rings offer enhanced sealing.

3. Dimensions : Make sure the seal dimensions (inner diameter, outer diameter, thickness) match your application perfectly to ensure correct installation and optimum performance.

4. Materials: Select seals made from materials suitable for the environment in which they will be used. For example, nitrile rubber (NBR) seals are suitable for general-purpose applications, while fluorocarbon (FKM) seals offer enhanced resistance to chemicals and high temperatures.

Benefits of pneumatic seals for various industries

• Automotive: Used in braking and air suspension systems, they ensure reliable sealing under high pressures and difficult operating conditions.

• Manufacturing: Essential for production equipment using pneumatic systems, where effective sealing is crucial to maintaining machine pressure and efficiency.

• Aerospace: Used in aircraft pneumatic systems to ensure reliable sealing under extreme pressure and temperature conditions.

• Medical: Used in pneumatically-operated medical equipment, such as respirators and anesthesia machines, where a perfect seal is required to ensure safe, smooth operation.

Pneumatic seals are essential components for any application requiring reliable, durable sealing under pressure. Available in a range of types and materials, they can be adapted to a variety of industrial environments to ensure optimum performance of pneumatic systems.
