Product Questions & Answers (3)

Question by: Merle R on Oct 6, 2025, 2:47 PM
got a hose end with a 1/2-14 female swivel on it, will this adapter let me step up to a 3/4-14 male npt without any goofy angle stuff
Answer by: Customer Support on Oct 8, 2025, 10:52 AM
Function-wise, it is a straight steel adapter that goes from a 1/2-14 female NPT swivel (NPSM internal pipe swivel) over to a 3/4-14 male NPT (NPTF external pipe). Since it is a straight style, it does not add an angle change, it just changes the thread ends.
Question by: Roger B on Aug 4, 2025, 1:09 PM
Will this adapter hold up in a marine environment? I'm rigging up some hydraulic lines on my boat.
Answer by: Customer Support on Aug 6, 2025, 6:02 AM
This Eaton Aeroquip adapter is suitable for marine applications, as well as chemical processing, pulp and paper, and even off-shore drilling. It's built to handle tough conditions.
Question by: Dwayne R on Apr 29, 2025, 9:30 PM
Got a 3/4 male NPT port on a manifold block and need to step down to a 1/2 female swivel connection, this adapter do that?
Answer by: Customer Support on May 1, 2025, 9:59 AM
That's what this one's built for. The male end threads into your 3/4-14 NPT port, and the female swivel end accepts a 1/2-14 NPT fitting. The swivel feature on the female side lets you rotate the mating connection during assembly so you're not torquing your hose or line to get alignment right. Straight configuration, so no angle changes in the hydraulic connections path.
