I see a simple product here; (2) machined aluminum plugs with o-rings,

small

plate secured by two screws above it.

Yep. That will work.

i plan to install a belly scoop on my -8.  i think i can route the plumbing
under the cabin floor.  what do people think about running simply radiator
hose vs some type of aluminum?  i planned to use 1" inside dia. hose or
pipe.  does flex aluminum come in 1", maybe for A/C uses perhaps?  that
would eliminate fittings and potential leaks although i would have to
insulate it i would guess.  any ideas?   kevin  3 rotor turbo'd

Not recommended Kevin. The water pump might not be up to it and it is hard
to duct air in and out of the heat exchanger. You will not be able to get
a suitably shaped (thin, large area) rad in a pod under the engine. If 
the rad is too thick sufficient air will not flow through it. Cutting large holes 
in the RV8 fuse and putting the rad in the aft fuse would be a bad idea. 

Running the pipes through the cockpit with hose or other joints is 
also a bad idea as a leak can cause scalding water in the cockpit. No fun.

Also you will have the additional drag of the belly scoop. There is plenty 
of room in an RV8 cowl for one horizontal rad and an oil cooler under the engine. 
Simple and short plumbing. Direct air in an out of the rad. Optimum minimum 
drag solution for cooling the rotary. Our biggest problem.
