Steel Adapter, 3/8-18 Male NPT Branch To 9/16-18 Male JIC 37 deg Flare Run, Tee

Description & Features

This zinc-plated steel tee adapter connects a 3/8-18 Male NPT branch port to dual 9/16-18 Male JIC 37° flare run ports, making it well suited for hydraulic, instrumentation, and chemical processing systems where a tee configuration is required. The SAE 37° flare ends on the run side provide a reliable metal-to-metal seal, while the NPTF branch thread offers a secure tapered pipe connection. Rated for a minimum working temperature of -65°F, this adapter handles demanding service conditions across a broad temperature range.

Manufactured under the Danfoss Power Solutions (Aeroquip) product line and catalogued as model C1AX52, this fitting carries a tube O.D. of 0.38 in. and a drop dimension of 1.22 in. The zinc plating provides corrosion resistance appropriate for industrial fluid power applications. No thread sealant is pre-applied, so appropriate sealant or tape should be used on the NPT branch connection at installation.

Question by: Gene P on Oct 6, 2025, 9:51 PM
got a tee with 3/8-18 npt on the branch and 9/16-18 jic on the run, is that what this one is?
Answer by: Customer Support on Oct 8, 2025, 8:09 AM
For SKU 2030-6-6S, the branch connection is 3/8-18 male NPT and the run connections are 9/16-18 male JIC with a 37 degree flare. It is an Eaton Aeroquip 2030 Series tee adapter in zinc plated steel.

Will this tee adapter work for hydraulic systems, or is it just for instrumentation?
Answer by: Customer Support on Aug 14, 2025, 6:33 PM
It's good for hydraulic, instrumentation, and even chemical processing systems, according to the description.
Question by: Tammy S on Sep 28, 2025, 9:07 AM
what's the thread setup on this tee exactly -- is the branch a pipe thread and the run a flare, or the other way around?
Answer by: Customer Support on Sep 29, 2025, 1:14 PM
The branch port is 3/8-18 male NPT and the run port is 9/16-18 male JIC 37 degree flare. So yes, you've got two different thread types on the same fitting. That kind of mixed configuration is pretty common when you're tying a pipe-threaded line into a JIC flare circuit without adding extra adapters in between.
