Question by: Sheila C on Nov 16, 2025, 12:56 PM
what industries is this adapter actually used in? trying to figure out if it fits what we're doing on the processing side of things
Answer by: Customer Support on Nov 18, 2025, 6:15 AM
Marine and military applications use it, along with chemical processing, pulp and paper, food and beverage processing, and offshore drilling. It covers a pretty wide range of heavy-duty industrial environments, so processing work is right in line with what this fitting is built for.
Question by: Earl H on Apr 12, 2025, 10:56 AM
Will this fitting work okay for connecting a quarter-inch NPT male to a nine-sixteenths SAE flare?
Answer by: Customer Support on Apr 13, 2025, 11:44 AM
Yes, this Eaton Aeroquip adapter is specifically made to connect a 1/4-18 male NPT to a 9/16-18 male SAE 45-degree flare. It's a 45-degree elbow style.
