Question by: Janet W on Dec 9, 2025, 4:38 PM
thread sizes on this one got me second-guessing myself, the female end is 7/16-20 and the male end is 1/8-27, that right?

You've got it. The female SAE O-ring boss end runs 7/16-20 thread, and the male NPTF end on the other side is 1/8-27. Both are standard sizes, so if your ports match up to those specs, this fitting connects them straight through without any adapters in between.

got a hose end with a 7/16-20 female ORB, will this screw right into it and give me 1/8-27 NPTF on the other side?
Answer by: Customer Support on Apr 2, 2026, 6:31 PM
For matching threads, it’s a straight steel adapter with a female SAE O-ring boss end in 7/16-20 (SAE J514) and a male NPTF end in 1/8-27 (SAE J476), so it bridges those two connection types.
