The T Plus 2 pipe thread sealant has a lot of good reviews. Should do the trick.
No problems with the Pex crimps. I'm using some full-sized tools now.
The leak before was the two piece brass-to-Pex fitting. The one piece fitting is the right one.

I started of buying the wrong part for this application..
In reading the reviews on the T+2 sealant, I saw a lot of people say the tape failed, but the T+2 worked fine.
The order should be here by Monday 17:30 and the oil burner will be off-line by the Tuesday noon..
