Got a line running 1/2 NPT female and need to drop it down to a 1/4 female NPT port. This straight union do that job?

That's what this adapter is built for. One end is 1/2-14 female NPT and the other is 1/4-18 female NPT, both in a straight configuration. So it'll bridge those two thread sizes without any bends or offsets in the line.

got a line with 1/2-14 female NPT and i need to step down to 1/4-18 female NPT, is this the right straight coupler?

For a straight pipe-to-pipe connection, it matches 1/2-14 Female NPT on one side and 1/4-18 Female NPT on the other, both female. It is a rigid straight union style adapter meant to join those two NPT thread sizes.
