Question by: Patty H on Aug 23, 2025, 7:37 PM

what's the thread setup on this fitting -- one end ORB and the other NPTF, or am I reading that wrong?

Answer by: Customer Support on Aug 25, 2025, 6:49 AM

You're reading it right. The female end is a 1-1/16-12 SAE O-Ring Boss port, built to SAE J514. The male end is a 1/2-14 NPTF, built to SAE J476. So yeah, it bridges those two thread standards in one straight fitting, which comes in handy when you're connecting an ORB port on a valve or manifold to pipe-threaded hardware on the other side.

Just want to make sure this will fit... I've got a female SAE O-ring boss and need to adapt it to a male NPTF. Will this do the trick?

Answer by: Customer Support on Dec 10, 2025, 6:08 AM

Yes, this straight adapter fitting is designed to connect a Female SAE O-Ring Boss port to a Male NPTF threaded connection. The ORB end conforms to SAE J514 and the NPTF end meets SAE J476.

got a port that takes a 1-1/16-12 ORB, will this adapter get me over to 1/2-14 NPTF on the other side?

Answer by: Customer Support on Nov 22, 2025, 6:41 AM

It bridges those two thread standards in one straight fitting. The female end is SAE O-Ring Boss per SAE J514 with a 1-1/16-12 thread, and the male end is NPTF per SAE J476 with a 1/2-14 thread.
