Key Benefits
Below are key benefits that highlight why metal seals are increasingly favored for their exceptional performance and environmental sustainability:
- Temperature Resistance:
- Metal seals perform exceptionally well in high-temperature environments, often exceeding 1,000°F (538°C), far beyond the limits of most elastomeric seals.
- This makes them ideal for applications such as aerospace, oil and gas, and high-temperature industrial processes.
- Chemical Compatibility:
- Metal seals are compatible with a wide range of aggressive chemicals, including acids, bases, and solvents, where elastomeric seals may degrade or fail.
- Leak Tightness:
- Advanced metal seal designs provide excellent sealing performance under extreme conditions, offering a helium leak rate of 1x10⁻¹⁰ cc/sec or better.
- Durability and Longevity:
- Metal seals are less prone to wear, aging, and degradation over time, offering a longer service life than elastomers, particularly in harsh environments.
- Pressure Handling:
- Metal seals withstand high-pressure applications, often exceeding 20,000 psi, while maintaining seating load.
- Customization:
- Metal seals can be tailored to meet specific design and performance requirements, including shapes, coatings, and material combinations (e.g., Inconel, stainless steel, or other nickel alloys).
- Environmentally Friendly:
- Unlike PFAS, metal seals do not persist in the environment or pose risks of contamination, making them a sustainable sealing solution.
