Question by: Clint C on Jan 23, 2026, 9:21 AM

what's the thread setup on this adapter, male on one end and female on the other?

Answer by: Customer Support on Jan 24, 2026, 1:15 PM

That's how it works. The male end is a 3/4-16 SAE O-ring boss, which meets SAE J514. The female end is a 1/8-27 NPSM thread, compliant with SAE J476. So you've got two different thread types and two different sizes, which makes it useful for connecting mismatched ports in a hydraulic or fluid line setup.
