Question by: Rusty M on Feb 23, 2026, 6:28 PM
What's this adapter typically used for? I'm working on a chemical processing setup.
Answer by: Customer Support on Feb 25, 2026, 3:51 PM
Often found in chemical processing environments, this Eaton Aeroquip adapter is also suitable for marine, military, pulp and paper, and food/beverage applications.
Question by: Ross F on Dec 27, 2025, 10:51 AM
got a hose end with a 3/4-14 female swivel on it, will this adapter mate up and go to a 1-11-1/2 male pipe thread?
Answer by: Customer Support on Dec 28, 2025, 6:27 PM
Built for that exact thread change, it goes from a 3/4-14 female NPT swivel (NPSM internal pipe swivel style) over to a 1-11-1/2 male NPT external pipe thread in a straight adapter.
