I'm needing a fitting that'll step up the size on my hydraulic lines. Will this do the trick for going from a smaller to a larger diameter?

This straight expander fitting features a male NPTF thread on one end and a female NPTF thread on the other, both measuring 3/4-14 per SAE J476. It should work as an adapter to connect different sized lines, provided those are the thread sizes you're working with.
