Question by: Neal F on Aug 28, 2025, 9:09 PM
got a valve port that’s 1/2-14 female npt. will this adapter let me step over to a 1-1/16-12 ORB fitting?
Answer by: Customer Support on Aug 30, 2025, 8:57 PM
Yes, it’s a straight steel adapter built to connect a 1/2-14 female NPT port on one side to a 1-1/16-12 male SAE O-Ring Boss straight thread on the other.
Question by: Troy H on Jul 27, 2025, 10:50 AM
Will this adapter work to connect a female NPT to a SAE O-ring boss? Just trying to make sure I get the right fitting for my hydraulic setup.
Answer by: Customer Support on Jul 29, 2025, 6:46 AM
This adapter is indeed designed to connect a 1/2-14 female NPT to a 1-1/16-12 male SAE O-ring boss. It's a straight adapter, so it'll give you a straight-line connection.
Question by: Ronnie M on Nov 26, 2025, 9:42 PM
what industries is this adapter typically used in, and does the steel construction hold up in tougher environments?
Answer by: Customer Support on Nov 28, 2025, 6:30 AM
Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this fitting. Steel construction is a solid choice across those environments since it handles the mechanical stress and exposure conditions common in those industries. The Eaton Aeroquip 2216 series has a well-established track record in heavy-duty and corrosion-prone settings, so it's a practical pick for demanding work.
