Steel Adapter, 1-5/8-12 Male JIC 37 deg Flare Branch To 1-5/8-12 Male JIC 37 deg Flare Run, Tee

It is a 2033 Series tee adapter with three SAE 37 degree JIC flare male ends. Both the branch and the run are 1-5/8-12 male JIC 37 degree flare, so you are matching the same thread and flare style on each connection.

Both ends of this adapter are 1-5/8-12 male JIC 37 degree flare, so yes, the thread and flare spec match up for exactly that kind of branch connection. The run port and the branch port share the same size, which makes it a straightforward drop-in for a same-size tee configuration. It's steel construction, part of the Eaton Aeroquip 2033 series, so it's built for hydraulic service rather than light-duty hydraulic connections work.

Hydraulic is the primary use, but this fitting is also rated for instrumentation and chemical processing systems. So if you've got a line running through any of those applications, it should serve you well. The 37-degree JIC flare connection is pretty standard across a lot of industrial fluid work, which is part of why it crosses over into those other areas.
