Glass-to-Metal Seals

Our principles of quality, precision engineering and attention to detail apply to all our glass to metal seals.

Using a wide range of materials and manufacturing capabilities, Martec provides custom designed solutions for glass to metal seals and electrical feedthroughs with advanced sealing techniques and on-site plating facilities.

Seals can be supplied in multi pin preforms, or, for high pressure applications (up to 60,000psi), in individual glass beads. Quality programmes include advanced mechanical and electrical inspections as well as non-destructive testing and pressure testing. 100% leak testing can be carried out in house for failsafe hermeticity. Customers can choose from our standard product range or bespoke concept to supply solutions.
