Hermetic Connectors. Engineered to Endure.
U.S.-made MIL-DTL-38999 Series I–III hermetic connectors with glass-to-metal seals for aerospace and defense.
Built for Sealed Reliability
Hermetic performance, controlled manufacturing, and a clear path from drawing to delivered connector.
Why BoldX: Machining and hermetic connector manufacturing under one roof means fewer handoffs between precision components, glass-to-metal sealing, inspection, and documentation. We support build-to-print programs and second-source evaluations with practical engineering feedback.
Series I–III at a glance: MIL-DTL-38999 Series I connectors offer threaded coupling for rugged applications; Series II uses bayonet coupling for fast, secure mating; Series III provides triple-start threaded coupling with high-density layouts and strong vibration resistance. Hermetic variants use glass-to-metal seals to protect systems from moisture, pressure, and harsh environments.
Application fit: Aerospace, defense, space, and other critical systems may require qualification, material control, electrical testing, leak testing, and traceability. We review the drawing, applicable specification, quantities, and documentation requirements before quoting.
Catalog and configuration: If you have a preferred configuration or catalog reference, include it with your RFQ. We can help confirm series, shell style, contact arrangement, finish, keying, and sealing requirements.
