I just read a document which gave a chart according to the diameter of the PEX.
It looked to me like 3/4ths could be bent under 1 radii. I confess I don't
understand what that meant but it is clearly a much tighter radius. They didn't
mention anything about distortion of the shape, if that is permitted or not.
They did mention that an inch of slack should be allowed for contraction for
every floor level, 8 to ten feet and that care to avoid any abrasion should be
exercised.
I admit my experience with the stuff is very limited. It is though a simple
thing to kink the stuff.
They also warn against exposure to daylight and other forms of ultra violet.

I was under the impression that you could bend it a bit tighter than a
three foot radius. In my investigations into underfloor hydronic radiant
heating, PEX is often used. To be able to make a 180 degree turn from
one joist bay to the next, the maximum curve would have to be less than
about 29 inches. And that doesn't seem to be any problem at all.
