A Penny !!

As they say the proof is in the penny or is it pudding? As you can see the US penny is actually quite representative of the wall thickness of the Apollo thru-hull fitting pictured above. Again this was a brand new, off the shelf, 1" bronze thru-hull fitting purchased from Hamilton Marine.

In the photos below I measure the wall thickness of a seacock flange for the sake of comparison.
