Will this fitting hold up okay if I'm using it with brake lines?
Answer by: Customer Support on May 12, 2025, 9:25 PM
This brass adapter is designed for secure connections in systems using SAE standard 45-degree flare fittings. It should be compatible with brake lines that meet those specs.
Question by: Harold M on Sep 12, 2025, 7:34 PM
got a line with a 3/4-16 female SAE 45 flare on one end and need to step it down, is this the right adapter?
Answer by: Customer Support on Sep 14, 2025, 2:19 PM
For a straight SAE 45 degree flare to SAE 45 degree flare connection, this adapter matches 3/4-16 female threads on one side and 5/8-18 male threads on the other, so it fits that step-down thread change.
