My personal preference is Deutsch. They make many of the OEM connectors, etc

Have a look through that lot. They are available from AED. They are beautiful, waterprooof, vibration broof, all the options are available.
Otherwise, if you dont want plastic, Deutsch also make mil spec versions in metal. see Deutsch connectors for Defense-Aerospace, Industrial, Hermetic and Communications Applications from Deutsch ECD
Cheers!
