What industries is this adapter actually built for? Trying to figure out if it fits our application before I order.

Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this adapter. It converts a 1/8-27 male NPT thread to a 7/16-20 female SAE O-ring boss port, which shows up pretty regularly in hydraulic systems across those sectors where you need a reliable, leak-resistant transition between pipe thread and straight thread O-ring connections.
