Product Questions & Answers (2)

Question by: Daryl A on Feb 22, 2026, 8:09 PM
what size tubes does this fitting connect exactly, the 1-1/4 and the 1 inch side?
Answer by: Customer Support on Feb 24, 2026, 10:16 AM
Correct on both counts. The larger end handles 1-1/4 inch OD tube with a 1-11/16-12 thread, and the smaller end steps down to 1 inch OD tube on a 1-7/16-12 thread. So yeah, if you're running two different line sizes and need to tie them together straight, that's exactly what this fitting does.

trying to swap out a fitting, is FS2406-20-16 the straight one that goes from a #20 FORS to a #16 MORS?
Answer by: Customer Support on Oct 16, 2025, 6:03 PM
Yes. FS2406-20-16 is a straight FS2406 series fitting with a #20 FORS end using a 1-11/16-12 Brennan A1 thread, and a #16 MORS end using a 1-7/16-12 Brennan A2 thread.
