New setup- gas distributor is leaking

I got a new 4 keg setup from Midwest, and when I tested it for leaks last week, I found one. I thought I got it. Fast forward to kegging my first beer today, and it still is leaking. Any ideas on how to stop this leak so I can carb my beer?

The leak is on the 4-way distributor on one of the outlets, before the shutoff..

I un-screwed the outlet, re-wrapped it with plumber's tape (twice now), and screwed it in as tight as I can get it with pliers. It still is leaking.

Any ideas on what else I can do?

Get yourself some Stag Jointing Compound that will fix it

Return it. Midwest is very good about replacing defective products. My regulator was malfunctioning and they sent a replacement right away.

That's what I was afraid of. I was hoping to be drinking my mild by Wednesday, but I guess I won't be.

Thanks!
