In your opinion, the ePMP is waterproof if the cap not arrive to the end

Or I need to remove it and vulcanize?

I don't like when they have no cover on all the head. For my part what i do i cut a piece of inner tube rubber and i glue it over the antenna connector and drop it over the radio. So the rain not fall directly on it. Cheap and efficient :)
If you loosen the 'nut' around one of the antenna connectors on the radio and raise the washer underneath that you can see a red O-ring intended to seal the housing around the SMA connector. Generally I would trust that to hold out water unless the whole radio is submerged, at which point the antenna connector is the least worry...

The caps alone will let water in, and you'll end up with water ingress in the connectors.
These UBNT jumpers are actually semi-rigid cable (tin-soaked braid), so the cable itself is water-tight, and the connectors being soldered to the cable, makes water ingress trough the back less of a problem.
The main way water enters (in my experience) sma connectors is trough the screwhead due to impromer mating-torqueing. (Finger-tight is not enough.). You should always give it a quarter-turn with a wrench to make sure the rubber-seal inside the screwhead is properly set.
Particularly, after all that, i always fill the silicone cap with "liquid rubber / liquid insulating tape". When pushed in place the liquid rubber squeezes trough the front and the back of the cap sealing everything.
I have sites where we have condensation 300 days a year, running with installs like that for 5 years without a failure.
Self-amalgamating tape is good, but you have to be carefull and experienced to properly seal a fragile cable and small SMA connector, at times in tight and complicated spaces... Plus in cold days tape can give you a hard time.
I'll find some pictures and post here shortly.
