Ask A Question

Description & Features

Manufactured by Eaton Aeroquip, this straight steel adapter connects a 1-14 Male SAE O-Ring Face Seal (ORS) thread to a 3/4-14 Male NPT thread, making it a practical solution for joining SAE O-Ring Face Seal and NPT-threaded components within a single inline assembly. The FF2031T Series is part of the FF2031T1012S, designed for straight-through flow with no angular offset.

Suited for demanding environments, this adapter sees use across marine and military, chemical processing, pulp and paper, food and beverage processing, and offshore drilling applications. The ORS end provides a leak-resistant metal-to-metal seal with an O-ring at the face, while the NPT end offers broad compatibility with standard pipe thread ports and components.

The catalog reference number for this part is C1EC85. For fluid compatibility guidance, refer to the Eaton documentation available through the product page resources.

Product Questions & Answers (3)

Question by: Patty F on Aug 12, 2025, 2:53 PM
got a port that’s 3/4-14 npt on one side and an ORS hose end on the other, is this the right adapter to tie them together?
Answer by: Customer Support on Aug 13, 2025, 5:59 PM
For tying an SAE O-Ring Face Seal male connection to a male NPT connection in a straight, inline run, this adapter matches that job. It has a 1-14 male SAE ORS thread on one end and a 3/4-14 male NPT thread on the other, so it is meant to bridge those two thread types in the same assembly.
Question by: Carl H on Nov 3, 2025, 6:32 PM
Will this here adapter work to hook up a SAE O-ring fitting to a regular NPT pipe thread?
Answer by: Customer Support on Nov 5, 2025, 5:38 PM
That's exactly what this Eaton Aeroquip adapter is designed to do: connect a 1-14 Male SAE O-Ring Face Seal (ORS) thread to a 3/4-14 Male NPT thread. It lets you join those two different kinds of fittings together.
Question by: Hugh M on May 21, 2025, 9:05 PM
Got a port on my hydraulic manifold that's 3/4-14 NPT and I need to tie into a SAE ORS line coming off the pump, this adapter cover that situation?
Answer by: Customer Support on May 23, 2025, 3:38 PM
That's what this one's built for. One end is 1-14 Male SAE O-Ring Face Seal, the other is 3/4-14 Male NPT, and it runs straight through with no angle offset. The ORS end seals against the face using a metal-to-metal contact with an O-ring, so you get a tighter, more leak-resistant connection than a standard pipe thread alone would give you. As long as your manifold port is a female 3/4-14 NPT and your hose or tube fitting is a female 1-14 ORS, this adapter drops right into that gap.
