What Hermetic Solutions Group does

Hermetic Solutions Group, founded in 1945 and headquartered in Feasterville Trevose, Pennsylvania, is a privately held U.S. supplier of hermetic packaging components and high-reliability interconnect solutions. Operating under the Qnnect corporate umbrella, the company runs six specialized business units — PacAero (hermetic assemblies and packages), Hi-Rel (specialized metal components for microelectronic packaging including getters, absorbers, covers, ring frames, thermal management solutions, and preforms), PacAero Agawam (microwave packages, hermetic sealing, advanced laser services), PacAero Norton (custom hermetic packages for microelectronic, fiber-optic, microwave, and optical applications), PacAero Mission (hermetic connector design and manufacture), plus the interconnect units Cristek (micro/nano-miniature connectors), Meritec (signal integrity interconnects), FilConn (filtered military/aerospace connectors), and Connectronics (RF/microwave connectors). Its core technology centers on hermetic sealing processes, specialty metallurgical components, and miniaturized interconnect engineering designed to protect sensitive electronics in extreme operating environments.

The company sells engineered hardware primarily into aerospace and defense, with secondary exposure to medical, energy, and broader microelectronics end-markets. The business model is B2B hardware sales conducted through direct enterprise field sales via the six subsidiaries, with an engineer-to-engineer consultative engagement model rather than self-service or channel-led distribution. Pricing is not publicly disclosed and is negotiated product-by-product through the individual businesses. Customer engagement flows through the corporate website (qnnectnow.com) and the websites of each subsidiary.

Hermetic Solutions Group is identified as a key participant in the global glass seal market, which is forecast to grow from USD 2.1 billion in 2026 to USD 2.8 billion in 2033 at a 4.2% CAGR. Its primary sub-segment, aerospace and defense, leads the market with a 25% share and an 8% CAGR, supported by global defense spending exceeding USD 740 billion in 2024. Recent strategic activity includes the October 2025 partnership with an aerospace OEM and the January 2021 acquisition of Cristek Interconnects, indicating an active posture of capability expansion in its highest-growth vertical. Leadership is held by Keith Barclay as President and CEO.
