25-Piece Military-Style panel-mount RF connectors RF straight bulkhead Connector Lot – Marked 74868 M39012/421-000L
$74.99
Lot of 25 military-style RF coaxial straight bulkhead / panel-mount connectors from surplus RF inventory. The connectors are marked 74868 M39012/421-000L and feature a threaded panel-mount bulkhead section with retaining hardware, metal right-angle body, white dielectric insulator, front RF jack interface, and rear center termination contact. These are excellent candidates for RF test fixtures, shielded enclosures, radio chassis projects, military-surplus restoration, custom coax assemblies, bench adapters, and experimental RF work.
The photographed lot appears clean and unused-looking, with mounting hardware present on many pieces. Exact mating connector series, impedance, frequency range, plating, power rating, and cable/termination specification are not verified and must be confirmed by the buyer before purchase or installation. Sold as a 25-piece mixed surplus lot exactly as pictured.
M39012-marked RF hardware is associated with military-specification coaxial connector families used in communications, avionics, laboratory equipment, test systems, and ruggedized electronic assemblies. These surplus bulkhead connectors are useful when a project needs a durable panel-mounted RF feedthrough or right-angle chassis connection.
Pipeline quantities are informational and may change after arrival, inspection, sorting, testing, or donor teardown.
Compatible Radios / Boards
Suitable for RF chassis, test fixtures, shielded enclosures, radio projects, military-surplus restoration, custom coax assemblies, laboratory equipment, antenna systems, and bench hardware where the buyer verifies the exact mating connector series, panel-hole dimensions, mounting hardware, center-contact style, impedance, frequency requirements, and termination method. Not a universal connector substitution. Buyer must confirm fit and electrical requirements before installation.
