Microscopic leak from compression fitting on refrigerator line

[incubusfan]

Looking to split the water supply behind my fridge and route to my coffee maker as pictured. All the other connections are watertight with no leakage whatsoever, however this one connection is dripping about 5 drops an hour. The leakage seems to be coming from the connector side and not the male splitter side.

I have tried tightening by hand, +1/2, and as tight as humanly possible still with residual weeping. Tried with/without Teflon tape. I have swapped out the hose as well, should I try a third hose or new splitter? Any putty that may help?

Thanks in advance for any assistance as I am a new DIY'er!

Teflon is inappropriate for those connections. They rely either on ground joint connection or use an internal rubber washer. If it leaks, it must be wholly replaced.
I've never seen a brass tee needing to be replaced.

It ended up being a faulty hose. Used a THIRD hose, no Teflon, hand tightened + 1/2, did the trick.
Thank you!
