Question by: Ross C on Feb 11, 2026, 7:16 AM
got a tee with one male npt run and a male jic 37 flare on the other leg, is that what this 2028-16-16s is?
Answer by: Customer Support on Feb 13, 2026, 6:31 AM
For tying those two connection styles together, yes. It is a steel tee adapter with a 1-11-1/2 male NPTF on the run and a 1-5/16-12 male JIC SAE 37 degree flare on the run and branch.
Question by: Merle P on Feb 12, 2026, 7:24 PM
got a line that's running 1-inch NPT male on one end and needs to branch off with a 1-5/16-12 JIC male fitting, this tee handle that kind of setup?
Answer by: Customer Support on Feb 14, 2026, 6:42 AM
That's exactly what this fitting is built for. The run ports are 1-11/2 male NPT and the branch comes off as 1-5/16-12 male JIC 37 degree flare, so you've got both connection types covered in one piece. It's a steel tee from Eaton Aeroquip's 2028 series, meant for hydraulic, instrumentation, and chemical processing lines. The NPT side threads into a female pipe port and the JIC end connects to a standard 37 degree flare fitting. Solid choice for splitting a line where you've got mismatched thread types on either side.

Will this tee fitting hold up in a hydraulic system on a tractor?
Answer by: Customer Support on Sep 13, 2025, 8:06 AM
It's designed for hydraulic, instrumentation, and chemical processing systems, so it should be suitable for a tractor's hydraulic system, assuming the pressure and media are compatible.
