Question by: Scott P on Sep 26, 2025, 11:31 AM
trying to swap an old adapter out, is this the one with 13/16-16 on one end and 1-5/16-12 on the other?
Answer by: Customer Support on Sep 27, 2025, 7:58 PM
For a straight adapter with those thread sizes, this part matches. The A thread is 13/16-16 and the B thread is 1-5/16-12, both on the FS6400-O series 08MFS-16MAORB configuration.

what's the tube O.D. on this fitting and does the hex size give you enough room to torque it down proper in a tight spot?
Answer by: Customer Support on Jan 29, 2026, 8:31 AM
Half-inch tube O.D. on this one. The hex comes in at 1.500 inches, so a standard 1-1/2 inch wrench fits it without any drama. Whether that gives you enough clearance depends on your setup, but that hex size is pretty workable in most install situations where space isn't extremely cramped.

Hey, just wanna make sure this thing'll fit. The dimensions listed are for the whole thing, right?
Answer by: Customer Support on Mar 21, 2026, 8:37 AM
Yes sir, the listed dimensions, including the 1.788" overall length and the 1.500" H Hex, represent the complete adapter size. So you can count on those measurements for fit.
