Product Questions & Answers (2)

Question by: Kent R on Feb 7, 2026, 2:41 PM
trying to hook a pipe port to an SAE o-ring boss line, is this the straight adapter for that?
Answer by: Customer Support on Feb 9, 2026, 2:35 PM
It bridges a female NPT pipe thread on one end to a male SAE O-Ring Boss straight thread on the other, and it’s a straight (non-elbow) adapter in the Eaton Aeroquip 2216 series.
Question by: Danny M on Jun 15, 2025, 7:35 AM
what industries is this adapter typically used in, and is it built to hold up in rougher environments?
Answer by: Customer Support on Jun 16, 2025, 5:27 PM
Marine, military, offshore drilling, chemical processing, pulp and paper, and food and beverage use are all listed applications for this fitting. Steel construction holds up well across those environments, and the SAE O-ring boss end gives you a reliable seal that handles the kind of vibration and pressure cycling those industries tend to throw at hydraulic lines on a regular basis.
