Built from resilient steel, this adapter should offer good durability for typical farm hydraulic applications.
Question by: Janice H on Oct 10, 2025, 11:41 AM
Got a line running 3/4 NPT male coming off a pump and need to tie into a JIC 37 female swivel fitting on the hose end. This the right adapter for that swap?
Answer by: Customer Support on Oct 12, 2025, 8:28 AM
That's what this one's built for. One end is 3/4-14 male NPT and the other is 7/8-14 female JIC 37 degree flare swivel, straight configuration. As long as your hose end is a 7/8-14 female JIC 37 degree flare, you're looking at a direct fit. The swivel on the JIC side makes alignment a lot easier during install, which helps in tighter spaces where you can't always get a clean straight-on connection.
