Question by: Tammy R on Feb 16, 2026, 10:28 AM

got a tight spot on my lines. is this the 90 degree elbow that goes from 9/16-18 male ORFS over to 7/16-20 male SAE O-ring boss?

Answer by: Customer Support on Feb 17, 2026, 3:42 PM

Matches that layout. One end is 9/16-18 Male SAE O-Ring Face Seal, and the other is 7/16-20 Male SAE O-Ring Boss with a straight thread O-ring, built as a 90 degree elbow.

Question by: Vince Y on Jul 19, 2025, 11:08 AM

Will this here fitting hold up okay in a marine environment, say on a fishing boat?

Answer by: Customer Support on Jul 21, 2025, 7:55 AM

This Eaton Aeroquip adapter is indeed well-suited for marine applications, along with chemical processing, pulp and paper, food and beverage, and even offshore drilling.

Question by: Tony T on May 3, 2025, 9:02 AM

got a 9/16-18 ORF seal fitting on a hydraulic line and need to drop down to a 7/16-20 ORB port on a valve block, this elbow gonna make that connection work?

Answer by: Customer Support on May 4, 2025, 3:53 PM

That's exactly what this fitting handles. One end is a 9/16-18 Male SAE O-Ring Face Seal and the other is a 7/16-20 Male SAE O-Ring Boss, so you're connecting two different thread and sealing standards in one piece. The 90-degree angle also takes care of routing in tight spots where a straight adapter just won't clear. It's made by Eaton Aeroquip, and the overall envelope runs about 1.29 inches on the long side with a 0.85-inch width, so measure your clearance before you button everything up.
