Question by: Ray M on Jan 8, 2026, 6:00 PM

What size threads am I working with on each end of this adapter? Got a fitting situation I'm trying to sort out before I order.

One end runs a 1-5/8-12 Male JIC SAE 37 Degree Flare, and the other is a 1-5/16-12 Male SAE O-Ring Boss. Both threads conform to SAE J514, so if your ports and hose ends are spec'd to that standard, you should be in good shape on both sides.
