part number FS1700-20-20 -- does that 1-11/16-12 thread pair up with a 1 1/4 inch flange port, or are those two separate connection points on this thing?

Question by: Debbie S on Aug 9, 2025, 12:39 PM

Both specs apply to the same adapter. The 1-11/16-12 is the thread size and it pairs directly with the 1 1/4 inch flange. That combination is what the FS1700-20-20 is built around, so if your port matches both of those dimensions you should have a solid fit.

So this adapter, it's for like connecting tubes and stuff, right? What size tubes does it actually fit?

Question by: Carl B on May 18, 2025, 6:16 PM

It's designed for tubes with an outer diameter of 1 1/4 inches. Make sure your tube size matches for a proper fit.
