Will this adapter work for connecting a 9/16-18 male fitting to a 3/4-16 female fitting?

Yes, this steel adapter is designed specifically to connect a 9/16-18 male SAE O-ring boss to a 3/4-16 female SAE O-ring boss, using straight thread O-ring adapters.

got a #6 male ORB port and need to step it up to a #8 female ORB, this bushing do that?
Question by: Brent O on Mar 4, 2026, 3:27 PM
That's what this fitting handles. The male end is 9/16-18 thread for your #6 ORB port, and the female end is 3/4-16 thread to accept a #8 ORB connection. Straight thread on both sides, O-ring sealing on both ends, so you're not relying on tape or sealant to hold pressure. Steel construction keeps it solid in working conditions where a softer material would give you trouble over time.
