It's from my head. I have a BVT - it's DC so the 4K is a DC claim. I
BVT cables used here in the shack as a fast way to ensure I don't have
some microscopic wire or filing or whatever down in a connector - stuff
like that is a nightmare to troubleshoot.
At one point I tried to use a PL259 for a HV run but it arced from time
to time at 4.2KV.
So at least in this shack, a PL259/SO239 is rated for well under 4KV.

Few of us can guarantee dry air for our antenna connections. Where is this data
from?
For the question “Has anyone tested them?”, I expect that Amphenol tests to the
published specs. Those tests would be over the entire temperature range in the
data sheet. If you visit the data sheets I linked for the UHF and type N
connectors, you might notice that type N has spect for many more attributes
than UHF.

5000 watts is 500 volts rms with a perfect antenna system. I suspect that
PL-259 connectors really can withstand much more than 500 volts. Has anyone
tested them? My station has a mixture of UHF, N and DIN connectors and all
have worked perfectly for 1500 watts HF. If PL-259s are failing they are
either poor quality connectors or there are serious antenna issues causing
excessive voltage.

From the Amphenol data sheet, UHF connectors are rated for 500 V peak, so they
are marginal for use at that power level. Type N connectors are rated at 1500 V
peak.
