D38999 connectors

Perhaps the most commonly used connector series in the military sector. Get in touch for either qualified MIL-DTL-38999 connectors or R.E.C. branded custom connectors.


MIL-DTL-38999, or D38999, connectors are the latest generation of circular military connectors. They are popular due to their compact size, high contact density, vibration resistance, quick coupling and environmental performance.

They come in four series:

Series I – (MS2746) – bayonet coupling – scoop proof

Series II – (MS2747) – bayonet coupling – low profile

Series III – (D38999/2) – threaded coupling – scoop proof

Series IV – (D38999/4) – Breech-lok (push-pull) – scoop proof

R.E.C. is a distributor of mil-spec D38999 connectors, but we also produce our own R.E.C. branded D38999 custom connectors.
