Water leak in threaded connectors

I am trying to replace the leaky water line to my evaporative cooler.
I made an adapter to go from the male end of a water hose to the 1/4"
copper line cooler connection. This worked with no problems for the
old water line for a decade or more. The adaptor is a brass round
piece that screws on the hose male connection with a center threaded
hole. Into the hole is a little brass adaptor from that
thread/diameter to a 1/4" copper-line compression fitting. I am
having water leaks at the threaded connections - hose, adapter and
copper-line connector - it's hard to tell exactly where the water is
coming from. I tried teflon tape - it helped a little but I still get
drip, drip, drip.

Any suggestions? Some sort of anti-leak fluid that will harden and
seal things? Something to put on threads in addition to or along with
the teflon tape?

TIA


Find the leak, then fix it.

Dry everything completely, then apply water pressure and start touching each
joint, looking for water on your finger. Once you find the leak, fix it.

Replace the washer of there is one in the joint.

For pipe threads, wrap them with 7 or more wraps of teflon tape, then tighten
securly. Or, coat the male threads with joint compound, then wrap with teflon.

For compression fittings, tighten them replace them, or possible try a thin
washer or teflon wrap on the contact surfaces.
