Solar water heater manifold hole diameter


New Member
I have a set of 58mm solar vacuum tubes that were taken from a discarded solar water heater and I want to build a new manifold using aluminum rectangular tubing.

I have the seals as in the picture, but what I am looking for is the diameter of the hole in the manifold for the seals and what is the thickness of the wall of a typical vacuum tube solar water heater tank. I do not have the old tank anymore so I can't take the measurement my self, but if someone has a dismantled one and can take some measurements it would be very helpful.
