In this video, we explore the engineering and performance of Glass to Metal Seals, focusing on their reliability and durability in demanding applications. You'll see how the matched thermal expansion coefficient between glass and metal ensures long-term stability, and learn about the 4J50 pin material and ELAN #48 glass that enable operation from -40°C to +150°C. We demonstrate the hermetic sealing capabilities and discuss real-world applications in automotive, aerospace, and industrial electronics where these seals provide critical electrical insulation and mechanical strength.
