6AN 수 플레어 to 암 플레어 스위블 티 스트레이트

Finally found a tee fitting that doesn’t leak no matter how I route the lines — the swivel action on the female side is smooth and locks tight. Used it to split my fuel return and it fit perfectly with no extra adapters needed.

The swivel on the female side makes tight engine bay routing way easier than a fixed tee, and the threads engage cleanly without any cross-threading. I've had it on my fuel line for a few weeks now and the flare seat holds pressure with zero drips.

The flare seat was perfectly machined, so the connection sealed on the first try without any leaks. Used it to split a fuel line under the hood, and the compact size let me fit it into a tight spot easily.
