Got a G 3/4 - 14 JIS port I need to cap off on a hydraulic manifold. This the right plug for that?

For a male G 3/4 - 14 JIS port, yes, that's exactly what this plug is built for. It's a steel Adaptall JIS plug with a 3/4 inch male side in that thread standard, so it should seat right into that port without any adapter needed. The 40mm length and 32mm wrench width give you enough to torque it down properly.
