what's the thread setup on this adapter, one end bigger than the other?

Answer by: Customer Support on May 28, 2025, 1:18 PM

the two ends are different sizes. One side is a male SAE O-ring boss threaded at 1-5/16-12, and the other is a female SAE O-ring boss at 1-5/8-12. Both threads meet SAE J514 spec, so if you're working with standard O-ring boss fittings on each end, this steps you up between those two sizes.
