what industries is this adapter typically used in
Answer by: Customer Support on Jan 23, 2026, 11:41 AM
Marine and military applications use it pretty regularly, along with chemical processing, pulp and paper, food and beverage processing, and offshore drilling. It's a Danfoss/Eaton Aeroquip piece, so it shows up across a wide range of demanding environments where a reliable pipe-to-flare connection is needed.
