Got a fitting that's 3/4-14 male NPTF on one end and need to step up to a 1-11-1/2 female NPTF port, this the right piece for that?

That's what this expander is built for. The male end is 3/4-14 NPTF and the female end opens up to 1-11-1/2 NPTF, so you're stepping from a smaller male connection into a larger female port in one straight fitting. Both threads meet SAE J476, so you shouldn't run into any compatibility headaches on standard NPTF hydraulic connections.

trying to step up from a 3/4 male pipe thread to a 1 inch female, is that what this expander does?

Function-wise, it is a straight expander that adapts from a 3/4-14 male NPTF thread on one end to a 1-11-1/2 female NPTF thread on the other, both per SAE J476.
