Did your stems have clamps?
When you say clamps, do you mean, the piece that goes in the hole on the outer tire, to hold the long valve stem in place?
If so, the answer is yes, we used those. They came with the dually valves in the form of a rubber oval-shaped piece that fit snugly into the hole and held the long dually valve in place (had a hole in center that valve stem came through). That was only thing the valves came with to hold it in place on the outside, and yes, we used them.
We did not have TPMS caps at ends, either. Never have been a fan of TPMS systems that mount onto end of valve stems.
The expansion and contraction of metals, or the differing metals wouldn't have anything to do with it, IMO, because there's a large rubber washer that's there at the mounting area to prevent that sort of failure modes.
That's what I thought, too, but was really at a loss for any other way to explain why those long stems kept leaking..
