The male plastic thread of the pump must have screwed up when screwing a brass tip: it's classic, metal tips are difficult to screw on plastic threads and damage them, the metal thread cutting the plastic thread. Most often we do not even realize it.
That said, the threaded end that comes out is long and makes it easy to attach a piece of pipe.
For my part, before attempting to remake a thread on the outlet end of the plastic pump (which risks weakening it), I would have first tried to fix in force a rubber end with a good clamp at the base, then a classic, Gardena or Plasson (for plymouth pipe) fitting at the other end of the pipe.
I have already been able to repair this type of problem using a piece of PE pipe (plymouth) with a diameter of 25 mm or 32 mm (the internal diameter of the addition must be less than the external diameter of the screwed-up nozzle), heated to l interior with lighter and screwed in force, blocked with a good collar: the plymouth is in Poly-Ethylene (PE) and easily melts which allows it to take the shape of the screwed thread and prevents leaks.
I add a detail: zooming in on your photo we see that the screw thread does not seem completely messed up (and that there is not a lot of Teflon: Teflon you have to put a few times a good thickness to seal the leaks). You can try to redo the thread by adjusting a female connector: you make the beginnings of the male and female threads coincide well by looking at where the threads of the threads begin, you press strongly by turning a little in the opposite direction clockwise (unscrewing) to force the correct positioning, and you try to get the threads back correctly to redo them .... is that clear? ...
