8AN 喇叭口螺母（適用於硬管）

The flare nut threads caught perfectly on the first try with my hardline tubing, no cross-threading or leaks. Nice snug fit that gave me confidence in the seal.

The threads on this 8AN flare nut are clean and consistent, which made seating it on the hardline a breeze. Once torqued down, the connection feels solid with zero leaks during my pressure test. Exactly what I needed for a reliable fuel line setup.

Took my time flaring the hardline and this nut threaded on smooth with zero binding, which is usually my biggest headache with AN fittings. The machining is clean and the flare seat lined up perfectly on the first try. Solid piece for the money, already ordered a second set for the other line.
