D38999/43YG41PN

D38999/43YG41PN is a DLA QPL qualified, MIL-DTL-38999 Series IV Hermetic, breech coupling, 38999/43 jam-nut mount receptacle. The Series IV offers the industry's most robust mating with a 90degree quarter-turn breech-lock mate with visual, tactile and audible engagement confirmation. The rugged construction of the D38999 Series IV connector disperses the mating force across a channeled metal flange while threaded mechanical force provides friction, locking the mating halves securely. The Series IV features accessory threads and environmental sealing for reliable attachment of back shells. The Series IV hermetics maintain seal integrity and prevent ingress of chemical substances or fluids in mission-critical vacuum environments where air or gas impurities can result in corrosion, dielectric breakdown, and loss of insulation resistance between conductors. Typical applications include medical, geophysical, military aerospace and other industrial applications.
