It’s a 2039 Series 90 degree steel elbow adapter with 3/4-16 male JIC 37 degree flare on both ends, so it’s meant to turn the line while staying JIC flare to JIC flare.

Food and beverage processing is one of the listed applications for this fitting, along with marine, military, chemical processing, pulp and paper, and offshore drilling. So for a food processing line, it falls within the intended use range. Both ends are 3/4-16 male JIC 37 degree flare, and it's built to Eaton Aeroquip's 2039 Series standard, which covers a pretty broad range of demanding industrial environments.
