Question by: Kurt B on Feb 25, 2026, 7:50 AM
got a hose end that’s 9/16-18 JIC, will this adapter let me tie into an SAE o-ring boss port the same size?
Answer by: Customer Support on Feb 27, 2026, 8:51 AM
For a straight connection between those two styles, it matches up as 9/16-18 male SAE O-Ring Boss on one end and 9/16-18 male JIC 37 degree flare on the other end, in a long straight steel adapter.
