Question by: Todd C on Aug 13, 2025, 10:47 AM
got a 3/4 tube line running off a manifold block and need to tee it off to a second circuit, this fitting work for that kind of setup?
Answer by: Customer Support on Aug 14, 2025, 1:00 PM
For a 3/4 tube OD application, the tube O.D. on this fitting matches right up at 3/4 inch. The run ports both carry a 1-3/16-12 thread on the A1 and A2 ends, with the branch port coming in at 1-1/16-12 on the B end. That combination of a straight run tee with a stepped-down branch thread is pretty common when you're splitting off to a smaller line or a different port type. As long as your manifold port and your branch connection match those thread specs, you'd be in good shape.
