The D38999/26FB4PN is a MIL-DTL-38999 Series III straight plug in shell size 11 with insert arrangement B4 carrying 4× #20 pin contacts, in Electroless Nickel finish with Normal keying. Series III is the highest-specification member of the 38999 family: a Tri-Start threaded coupling with an anti-decoupling ratchet, scoop-proof shell-to-shell engagement and a mated IP67 seal. It is the connector specified for airframe, engine-bay, ground-vehicle and naval harnesses that must survive continuous vibration and high mating-cycle counts, and it interchanges on a form, fit and function basis with the Amphenol, TE Deutsch and Souriau part numbers shown above. Airoadcon builds the cross-brand equivalent J599/26FB4PN with QPL-grade materials and free samples for qualification testing.
