Question by: Travis G on Nov 25, 2025, 1:32 PM
got a hose end with 1/2-20 JIC, will this straight adapter match up on both sides?
Answer by: Customer Support on Nov 27, 2025, 7:55 AM
Built as a straight Male JIC SAE 37 degree flare to Male JIC SAE 37 degree flare adapter, both ends are 1/2-20 threads and follow SAE J514.
Question by: Bobby E on Apr 14, 2025, 1:14 PM
Both ends are 1/2-20 male JIC on this thing, right? Trying to connect two female JIC fittings back to back and wanna make sure I got the right piece before I order.
Answer by: Customer Support on Apr 16, 2025, 11:45 AM
Correct on both counts. Each end carries a 1/2-20 Male JIC SAE 37 Degree Flare thread, so you're looking at a male-to-male straight union. If you've got two female JIC ports that need to be joined inline, this adapter is exactly what bridges them. Both ends conform to SAE J514, so thread geometry is consistent across the fitting.

Reckon this would hold up okay for hooking up some hydraulic lines on my tractor? Gotta be able to take some pressure.

This straight adapter is made from steel and can handle a maximum dynamic pressure of 6,000 PSI, so it should be suitable for many hydraulic applications.
