Hermetic Sealing With Ceramics and Glass


Whether your design requires glass-to-metal seals or ceramic to metal (Kryoflex®) hermetic sealing, PA&E delivers innovative, versatile, and reliable solutions that perform to the highest standards in a wide range of applications and environments.

Hermetic Sealing with Ceramic to Metal Seals

Hermetic 38999 Circular Connector
PA&E Provides Both Ceramic-to-Metal and Glass-to-Metal Hermetic Sealing

PA&E’s ceramic to metal seals incorporating the patented Kryoflex  polycrystalline ceramic, were created to replace conventional compression glass and metallized alumina ceramics for superior bonding properties. It is a unique material that relieves stress within itself and eliminates the most common causes of hermetic failure. PA&E’s Kryoflex hermetic seals system demonstrates superior electrical performance while withstanding mechanical and thermal stresses far beyond what glass to metal seals can endure. Kryoflex will directly seal into materials such as stainless steel, titanium, and aluminum.

Glass-to-Metal Seals

When required for a specific application, or utilized when a less-expensive manufacturing alternative to our Kryoflex hermetic seal is necessary, PA&E can also seal glass directly into most any iron/nickel alloy. Our glass-to-metal sealing capabilities allow for matched sealing, compression sealing, and Hi-Rel (High Reliability) sealing using special oxidation and requiring higher processing temperatures, can be used, depending upon individual package requirements. PA&E’s hermetic glass-to-metal seals meet or exceed MIL-STD-883 and JEDEC Spec 9A.
