got a 3/8 tube line, what thread is this long flare nut set up for?
Answer by: Customer Support on Nov 14, 2025, 7:12 PM
For a 0.38 inch tube outside diameter, this long flare nut uses a 5/8-18 thread, which is the size it is built around for making that flare-style connection.
Question by: Billy C on Feb 9, 2026, 2:45 PM
part number 41X6, is that the long nut version or the standard length? trying to make sure I grab the right one before I put in the order
Answer by: Customer Support on Feb 10, 2026, 6:40 PM
The 41X6 is specifically the long flare nut configuration. It's part of the Eaton Aeroquip 41x Series, and the "long" designation is built right into what this part is. If you were looking at a standard-length version, that would be a different part number within the same series.
