Product Questions & Answers (3)

Question by: Lance R on Apr 22, 2025, 11:33 AM
Will this adapter work for connecting an O-ring face seal to a straight thread O-ring?
Answer by: Customer Support on Apr 24, 2025, 10:05 AM
Yes, this Eaton Aeroquip adapter is designed specifically for that purpose, connecting an 11/16-16 Male SAE O-Ring Face Seal to a 7/16-20 Male SAE O-Ring Boss (Straight Thread O-Ring) fitting.
Question by: Kurt S on Mar 5, 2026, 3:37 PM
trying to swap an ORS end over to an o-ring boss port, is this the right adapter for that?
Answer by: Customer Support on Mar 7, 2026, 6:19 AM
For that kind of changeover, it fits the bill. It transitions an 11/16-16 male SAE O-Ring Face Seal (ORS) thread to a 7/16-20 male SAE O-Ring Boss (straight thread O-ring) connection, and it is a straight adapter for in-line routing.
Question by: Clint E on Jul 11, 2025, 8:35 PM
got a fitting on a pulp processing line running an 11/16-16 ORS port and need to step down to a 7/16-20 SAE O-ring boss connection, this the right adapter for that?
Answer by: Customer Support on Jul 13, 2025, 6:46 AM
That's what this one does. One end is 11/16-16 Male ORS and the other is 7/16-20 Male SAE O-Ring Boss, straight through with no angle. Pulp and paper is actually one of the listed applications for this part, so you're in the right ballpark. It's made by Eaton Aeroquip, part of their FF1852T series, and the SKU is FF1852T0604S if you need it for ordering.
