got a hose end that’s 9/16-18 JIC, and the other side needs to go into 1/4-18 pipe. is this the 90 degree elbow that’ll do it?

For a right angle hookup, it matches those thread sizes and end styles. One end is a 1/4-18 male NPTF swivel, and the other end is a 9/16-18 male SAE 37 degree (JIC) flare.

Chemical processing is one of the listed application areas for this adapter, along with marine, military, pulp and paper, food and beverage, and offshore drilling. The zinc plated steel construction and the Eaton Aeroquip 2249 series build are what make it suitable across those kinds of demanding environments. If chemical processing is your main use case, you're working within the intended scope of this fitting.

trying to hook a 1/4 npt line over to a 9/16-18 jic hose end, and i need it to turn the corner. is this the right adapter?

It’s a 90 degree elbow adapter that goes from 1/4-18 male NPT swivel on one side to a 9/16-18 male JIC 37 degree flare on the other, so it matches the thread sizes and the JIC flare style you described.
