Thread size on this one is 9/16-18, that right for a standard 06 JIC fitting?
Answer by: Customer Support on May 1, 2025, 10:02 AM
9/16-18 is correct for a -06 JIC tube nut. It conforms to SAE J514, which is the standard spec for JIC fittings across the board, so it'll match up with other SAE J514-compliant components at that dash size without any guesswork.
