         The environment need not be.  The JOINT must,

         for reliability.  Its the 'interior' of the
         joint.

         Detailed reading in electrical connection
         technology will encounter the use of the phrase

                 'gas tight'

         with regards to a a good (permanent) connection.
         ANY good connection (switching aside...) is 'gas
         tight' or has a portion which is.  A common
         screw connection makes a gas tight joint due to
         the clamping forces.  Ditto a 'wire nut'.
         A properly made joint is TIGHT and STRONG enough
         to stay that way.  (one of the benefits of
         soldering is that it seals the inside of the
         connection.)  A well made crimp connection
         'cold welds' the bits together, excluding 'gas'
         (Oxygen is the chief threat...)

         Al rated connectors include higher clamping
         forces (to maintain clamping forces to maintain
         tightness) and compatible materials (to maintain
         clamping forces and reduce corrosion.)
