General state of Conduit Fittings.  Advanced corrosion has developed between body and the cover,  totally destroying fittings.

Heavy salt deposits have caused rapid onset of corrosion, starting at most vulnerable point - joint between body and cover.

Heavily corroded (pneumatic) compressed air lines.  Note that lower pipe is an old redundant line, upper pipe is a replacement line.
