What sealing technology do you use?

Glass-to-metal sealing creates a robust hermetic barrier. We align leak testing, inspection, and documentation with each program’s requirements.

Can BoldX be a second source for an existing connector program?

Yes. We can evaluate second-source opportunities alongside established QPL suppliers while respecting your qualification, procurement, and documentation controls.

Do you support custom or build-to-print hermetic work?

Yes. Share the drawing or model, specification, quantities, and performance requirements for an engineering review and quote.

How do we start an RFQ?

Send your drawing or model, material and electrical requirements, quantities, and quality documentation needs. We will review the scope and provide a clear capability assessment.

MIL-DTL-83723 Hermetic Connectors. Built to Spec.

U.S.-made MIL-DTL-83723 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. Pair with our connectors capability page and the MIL-DTL-38999 hub.

83723 at a glance

MIL-DTL-83723 circular connectors are widely specified for aerospace and harsh-environment interconnects. The family includes environment-resistant designs with bayonet and threaded coupling options depending on series/style. Hermetic variants use glass-to-metal seals to protect systems from moisture, pressure differentials, and harsh environments when the application demands sealed performance.

Application fit

Aerospace, defense, 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. We match connector configuration to the application’s sealing, electrical, inspection, and documentation requirements.

Catalog and configuration

If you have a preferred configuration or catalog reference, include it with your RFQ. We can help confirm series/style, shell, contact arrangement, finish, keying, and sealing requirements.
