So if there tapered what coupler should I be using?

I would make sure of the fitting . water line rarely is exposed to 3000psi. The fitting would not be weeping if you had the correct set up. In some cases the tape can be dangerous floating around.

If the fittings are tapered, they are NPT, then use NPT fittings.

As far as Teflon tape on hyd fittings, it is general practice to not use it. The reason is that the tape will shred when loosen, and most people don't clean out the threads. and small bits of Teflon is pushed into the hyd flow and can jam up things in the hyd circuit.

Teflon paste is recommended or Loctite red or blue.

Npt fittings were not designed for repeated coupling, Each time you tighten, the threads are deformed a little more. Maybe 2 to 3 tightening and loosening.

Your best bet is to switch over to JIC fittings, and tighten the NPT one good time. JIC does not need Teflon.

You may have over tightened the fitting the very first time and deformed the threads too much and that's why they leaked
