Why? They might be less susceptible to mechanical damage.
Non-corrosive. They might float. They could be injection moulded in
China like everything else......

Subject: Flex Heads / Dissimilar Metals
I'm working on a job and the Engineer is rejecting our plans because
we are using flex heads, he is using a section in the spec for
Dielectric Fittings to justify his point. The only thing I can
possibly see him trying to get out of it might be something to do
with dissimilar materials? Any thoughts?
Help? Input?
