Parker Hannifin Metal Seals: Choosing the RIght Seal for Your Application

At Wyatt Seal, we are proud to offer a range of high-quality Parker Hannifin metal seals designed to meet the most demanding sealing requirements. These seals are engineered to perform under extreme conditions, providing reliable solutions for applications where traditional elastomeric seals might not suffice. Choosing the right metal seal involves considering specific application requirements, including seal profiles, operating temperatures, and material compatibility. By understanding these elements, you can select the most suitable seal to ensure optimal performance and longevity in your critical sealing applications.

Metal Seal Profiles

The profile of a metal seal is crucial, as it determines how well the seal can withstand different pressures, temperatures, and mechanical stresses, directly impacting its overall performance. Selecting the correct metal seal profile ensures a precise fit and optimal sealing, reducing the risk of leaks and failures in critical applications. Understanding the specific profile needed for your application is essential, as it influences the seal's ability to maintain integrity under varying environmental conditions and load demands. Discover Parker's innovative metal sealing profiles and learn when to use them for optimal performance in challenging applications:

C-Seal

1. Use: Ideal for high-pressure and high-temperature applications.
2. Features: Offers excellent resilience and is commonly used in aerospace and industrial gas turbines.

E-Seal:

1. Use: Suitable for applications requiring high spring back and leak tightness.
2. Features: Provides a higher level of elasticity compared to other metal seals, making it ideal for fluctuating pressures.

Spring Energized C-Seal:

1. Use: Ideal for applications with moderate to high pressures where a high level of elasticity is required.
2. Features: The spring energizes the seal, providing additional seating load and consistency.

U-Seal:

1. Use: Versatile and used in a wide range of applications, including cryogenic and high-temperature environments.
2. Features: Offers good sealing capabilities and durability.

Boss Seal (Metal):

1. Use: Designed for sealing in high-pressure and high-temperature applications, particularly in hydraulic and pneumatic systems.
2. Features: Ensures reliable sealing with excellent resistance to extreme conditions, commonly used in demanding industrial environments.

O-Ring:

1. Use: Commonly used in static and dynamic applications across various industries.
2. Features: Known for its simplicity and effectiveness in sealing a wide range of pressures and temperatures.

Axial C-Seal:

1. Use: Best for static applications where axial compression is needed.
2. Features: Excellent for sealing flanges and other components that require a tight seal under axial loads.

Temperature and Pressure Considerations

Parker metal seals are engineered to withstand extreme temperatures and pressures. Selecting the right seal profile depends on the specific conditions of your application:

1. High-Temperature Applications: C-seals, E-seals, and spring energized C-seals are designed to maintain sealing contact in extreme heat.
2. High-Pressure Applications: Boss seals and C-seals are excellent choices for environments with high-pressure demands.
3. Cryogenic Applications: U-seals perform well in extremely low temperatures, ensuring reliable sealing.
