got a 1/4 inch NPTF port on a manifold block and need to run a JIC line off it, this fitting do the trick?

That's exactly what this adapter is built for. One end is a 1/4-18 Female NPTF, so it threads right into that port. The other end is a 1/2-20 Male JIC with a 37-degree flare seat, which connects to your JIC hose or tube assembly. Rated to 6,000 psi, so it holds up well in most hydraulic circuits without issue.
