  • Both coupling styles inter-mate with MIL-DTL-83723 connectors (exception: shell size 8 threaded, does not mate with M83723 threaded).
  • Aluminum and passivated stainless-steel versions.
  • A variety of mounting configurations.
  • A variety of material finishes are offered such as electroless nickel, olive drab cadmium and black anodizing. Other finishes are available with a commercial equivalent.
  • Alternate key/keyway positions prevent cross mating of adjacent connectors having the same insert arrangement.
  • Positive alignment of pin contacts by the lead in chamfers of the closed entry hard socket inserts, for select Boeing products.
  • The elastomer grommet is able to seal over a wide range of wire diameters and has a triple wire seal in each cavity.
