Dave,
For the same reason ALL rubbers fail.....too much pressure too much 
heat! :-)

The rubber fitting that failed was a rubber drain boot connecting 
flexible hose (from the pump) to 1 1/8" copper tubing (on the heat 
exchanger). The replacement fittings adapted the 1 1/8" copper fittings 
to smaller NPT pipe so that the flexible hose could be slid over and 
worm gear clamped in place.

P.S. As to picture taking.....you give a whole new meaning to exposure 
and "f" stop!
