Question by: Janice C on Mar 23, 2026, 11:59 AM

got a #12 male ORB port on a manifold block and need to step it down to a #4 female ORB, this bushing gonna work for that?

Answer by: Customer Support on Mar 24, 2026, 9:29 PM

That's what this fitting is built for. The male end runs a 1-1/16-12 thread, which is your standard #12 SAE O-Ring Boss size, and the female end is 7/16-20, which is your #4 ORB. Straight configuration means no angle change, just a clean inline reduction between those two port sizes. Steel construction holds up well in working hydraulic environments, and the O-ring sealing on both ends takes care of the leak path without any thread tape or sealant needed.
