What size is this fitting? Just need to make sure it'll work with my existing setup.
Question by: Freddie B on Jul 9, 2025, 3:53 PM
It's an 08FFSS-08MORB straight adapter, so you'll want to check if that matches your requirements.

what's the difference between this part and one with a check valve built in, trying to figure out if it'll work for my setup
Question by: Jean T on Mar 29, 2026, 8:14 AM
Without a check valve, flow moves freely in both directions through the adapter. Nothing inside is blocking or regulating it. If your system needs flow restricted to one direction, you'd need a separate inline check valve elsewhere in the line. For connections where unrestricted flow is fine, this straight adapter handles that without any extra hardware getting in the way.

trying to swap out an old adapter, is this the one that matches FS6540-08-08-O?
Question by: Danny R on Jul 16, 2025, 9:51 PM
Match it up by the supplier part number. This adapter is listed as FS6540-08-08-O, and it also cross-references to MPN FS6540-08-08-O with an alternate part number of AFF2130T0808S.
