got a hose end with a 9/16-18 female ORB, will this screw right into it and then give me a 1/4-18 pipe thread out the other side?

Answer by: Customer Support on May 1, 2025, 3:41 PM

For hooking a female ORB port to a male pipe thread, this straight adapter is set up exactly that way. One end is 9/16-18 female SAE O-Ring Boss per SAE J514, and the other end is 1/4-18 male NPTF per SAE J476.
