SRI Hermetics was founded on the principle of using advanced engineering and material science to create the world’s leading hermetic electrical connectors and electronic packaging solutions. Since our inception, we have developed and introduced many new technologies to the industry, setting new performance standards and displacing the traditional methods of glass to ferrous alloy sealing. Our exclusive ceramic dielectric material, Ceramax, is one of the core technologies used to produce our advanced connector line. Ceramax is a multi-phase devitrified ceramic compound used as a direct replacement for glass. When fused to copper alloy or stainless steel contacts, Ceramax seals provide superior hermetic reliability in environments that would simply destroy competing products.

Concept Group, Inc. has over a 30-year history of supplying precision machined parts and assemblies for a variety of industries. In the mid-1980's, Concept refocused its business to specialize in high-performance Glass-to-Metal hermetic seals. Today, the foundation of Concept's business comprises four pillars: 1) hermetic Glass-to-Metal seals and assemblies, 2) Vacuum Insulated parts/assemblies, 3) Vacuum Brazing, and 4) Machining Services. With our own machine shop, engineering expertise, testing services, and plating operation we can deliver both highly customized and standard packages.
