Description & Features

Manufactured by Eaton Aeroquip, this straight steel adapter connects a 1-7/16-12 Male SAE O-Ring Face Seal (ORS) port to a 1-11-1/2 Male NPT thread, providing a reliable transition between these two common thread standards in a single inline fitting. The FF2031T Series is part of the FF2031T1616S configuration, with an overall dimension of 2.05 inches.

Suited for demanding fluid conveyance environments, this adapter sees regular use in marine and military systems, chemical processing, pulp and paper, food and beverage processing, and offshore drilling applications. The ORS end provides a leak-resistant face seal connection, while the NPT end accommodates standard tapered pipe thread ports.

Refer to Eaton's fluid compatibility documentation to confirm suitability for specific media before installation. Catalog number C1EC88 can be used for cross-referencing within Eaton Aeroquip literature.

Question by: Roy S on Jun 17, 2025, 6:43 PM
trying to hook up an ORS port to a pipe thread port. is this the right adapter if my ORS side is 1-7/16-12 and the other side is 1-11-1/2 male NPT?
Answer by: Customer Support on Jun 18, 2025, 9:01 PM
For that exact thread combo, yes. It is a straight steel adapter with a 1-7/16-12 Male SAE O-Ring Face Seal (ORS) on one end and a 1-11-1/2 Male NPT on the other, made to transition between those two standards in-line.
