In this video, we explore how industrial-grade glass-to-metal seals withstand extreme thermal cycling from -60°C to +100°C while maintaining hermetic integrity. Watch as we demonstrate the mounting screw installation process, analyze the 4-pin J50 configuration, and showcase impact resistance testing up to 200N. See real-world applications in aerospace, automotive, and electronics where these silvery SUS316 stainless steel seals deliver reliable performance in demanding environments.
