Question by: Dale E on Sep 12, 2025, 8:34 PM
What size is this fitting, for hose purposes?
Answer by: Customer Support on Sep 14, 2025, 7:21 AM
This adapter uses a -12 MFS (Male Fuel Swivel) connection on one side and a -08 MAORB (Male Adjustable O-Ring Boss) on the other. Be sure to match these specs to your hose and port sizes.

Got a spot on the line where I need a straight adapter going from a 12 MFS fitting to an MAORB port, this the one for that?
Answer by: Customer Support on Oct 2, 2025, 4:31 PM
That's what the FS6400-12-08 is built for. It connects a 12-size male flareless fitting on one end to a minus-8 male ORB port on the other, in a straight configuration. No adjustable end on this one, so you get a fixed, secure fit without needing to fiddle with positioning after installation. Brennan makes these to tight tolerances, so the connection comes out clean and stays that way.

trying to swap out an old straight adapter, is FF6400-12-08 the same thing as FS6400-12-08-O?
Answer by: Customer Support on Nov 21, 2025, 8:37 PM
For ordering and replacement, FF6400-12-08 is the SKU and FS6400-12-08-O is the supplier part number for the same Brennan Industries straight adapter.
