Description & Features

Designed for reducing connections in demanding hydraulic systems, the Steel Adapter, 1-5/16-12 Male SAE O-Ring Boss (Straight Thread O-Ring) To 1-1/16-12 Female SAE O-Ring Boss (Straight Thread O-Ring), Straight is a straight-configuration reducer adapter from Eaton Aeroquip's FF1010 Series. It transitions from a larger 1-5/16-12 male SAE O-Ring Boss port to a smaller 1-1/16-12 female SAE O-Ring Boss port, with an overall dimension of 1.59 inches at the A measurement.

Suited for a broad range of industrial environments, this adapter is commonly used in marine and military applications, chemical processing, pulp and paper facilities, food and beverage processing, and offshore drilling. The straight thread O-ring boss configuration on both ends provides a reliable, leak-resistant seal without the need for thread sealants. Steel construction ensures durability under the pressure and environmental conditions typical of these industries.

Question by: Danny W on Sep 21, 2025, 12:29 PM
got a 1-5/16-12 ORB port on my hydraulic block and need to step down to a 1-1/16-12 female connection. this the right part for that?
Answer by: Customer Support on Sep 22, 2025, 2:22 PM
That's exactly what this adapter is built for. The male end threads into your 1-5/16-12 SAE O-Ring Boss port, and the female end accepts a 1-1/16-12 SAE ORB fitting on the other side. Both connections use straight thread with O-ring sealing, so you get a clean, leak-resistant reducer in one piece without stacking multiple fittings.
Question by: Jimmy Y on Feb 20, 2026, 11:02 AM
Will this adapter work with standard SAE O-ring fittings?
Answer by: Customer Support on Feb 22, 2026, 6:46 AM
Yes, this adapter is designed to connect two SAE O-ring boss (ORB) fittings, a 1-5/16-12 male and a 1-1/16-12 female.
Question by: Steve S on Jun 22, 2025, 12:56 PM
Just want to make sure, this'll fit a standard 1-5/16-12 SAE O-ring port, right?
Answer by: Customer Support on Jun 23, 2025, 3:07 PM
That's correct. This adapter is designed to connect to a 1-5/16-12 male SAE O-ring boss port.
