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?

Answer by: Customer Support on Aug 11, 2025, 6:00 AM

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.
