Temper Corporation

High Temperature Metal Seals

exceptionally high operating resilience

Sealing applications exposed to temperatures up to 2000° F fall out of range of polymers, necessitating the need for high temperature seal materials. In 1971, Temper Corporation solved the problem by developing high temperature metal seals for use in the commercial and military aircraft industry. Our high temperature gaskets and seals now serve industries such as oil and gas refinery, power generation, and aerospace for various applications, including but not limited to:

  • Commercial and military aircraft
  • Fuel cells
  • Nuclear reactors
  • Oil refinery valves

High pressure seals are recommended as an alternative to standard seals in applications where corrosive elements put the longevity of gaskets at risk, where the temperatures are very high or very low, or in environments where a vacuum exists.

High temperature seals and high pressure seals resist leaking, cracking, brittleness, and loss of elasticity that is likely with polymers in these applications. We produce our high temp seals with various materials suitable for a range of applications.  

Types of Metal Seals

We utilize roll forming to create our multi-convolute and machined high temp seals, which are then coated with silver or gold for exceptional gas and fuel sealing performance. They can range in size up to 60+ inches and offer superior spring back up to .010 of an inch after compression, allowing for a tight seal within a component. Temper produces E-ring seals which are used in light load applications where high temperature resistance and flexibility are needed.

Sealing Materials for High-temperature Seals

At Temper Corporation, we offer high temperature seals using superior materials capable of withstanding temperatures up to 1450° F. Inconel provides excellent corrosion, oxidation, and creep resistance, as well as strength under high temperatures. Hastelloy is a nickel-molybdenum alloy that comes in a variety of grades for specific applications. All grades are hard and strong under high temperatures; highly ductile; and easily formed, fabricated, welded, forged, and cold worked.

The Benefits of Metal Seals

Choosing the right material for your sealing application is crucial in ensuring optimal performance. Metal seals offer the following benefits:

  • Ductility and hardness in load, spring back, and outer sealing can be optimized for reliable performance in each application.
  • Direct bonding minimizes failures and eliminates unnecessary parts.
  • Internal hydrostatic pressure allows metal seals to withstand high pressure without blow-by.
  • Reduction of thermal distortion reduces the risk of leakage.

Gaskets vs. Seals

Understanding the differences between gaskets and seals will help you choose the proper sealing device for your needs. Gaskets are a type of seal that prevents leakage by sealing the union between components or flanges with flat surfaces. They are typically used in static applications. Seals are commonly used in applications where a flat flange gasket wouldn’t properly seal the joint, such as between engine parts, pumps, and shafts that rotate.
