I used pvc for a similar purpose (standpipes inside the helm pedestal guard tubes). I don't know how strong the bond is, but the pvc doesn't budge, and no water was come in.

Thanks Davester. How did you secure and/or seal the PVC?

I drilled out the area, taped the bottom, put the pvc sections in place, and poured thickened epoxy around them. I was also replacing the pedestal guard feet which required drilling some new holes, and filling old ones. I didn't seal the inside the pvc tubes, but they aren't getting any water in them. (I have rubber gaskets where the wires enter the guard rail at the top).
