I eventually ended up using a length of brass tubing stock as a mandrel and wrapped it with fiberglass tape then applied resin to make fiberglass tubes. I then used resin to glue in the fiberglass tubes. After that was all done, I installed the brass tubes in the conventional manner. Now I know no matter if the o-ring seal fails or the brass just rots out, the hull is still about as water proof at the tube locations as I'll ever get it.
