what all is this tee adapter meant to be used on? asking cause we run a mix of hydraulic and instrumentation lines and trying to figure out if it fits our setup
Answer by: Customer Support on May 30, 2025, 10:49 AM
Hydraulic systems, instrumentation lines, and chemical processing applications are all listed uses for this fitting. The 9/16-18 JIC 37-degree flare connections on all three ports make it a solid match for any hydraulic connections that already runs that thread and flare standard. If your lines are already JIC 37, you're in good shape.
