Daniel X. ★★★★★ Oct 22, 2026

The inverted flare side threaded onto my brake master cylinder perfectly with no binding, and the AN end sealed up tight on the first try. Exactly what I needed to adapt my hard line to a -6 hose.

Jason ★★★★★ Oct 21, 2026

Threads on both ends are clean and cut properly, no cross-threading when I torqued it down. Fit my 6AN line to the stock 5/8"-18 fitting without any leaks on first try.

Brian H. ★★★★★ Oct 20, 2026

Took a while to find an adapter that actually bridges 6AN to the 5/8"-18 inverted flare, and this one threads on smooth with no wobble. The flare seating feels solid once torqued, so I’m confident it’ll hold pressure on my fuel line without weeping.
