Question by: Glen P on Feb 14, 2026, 9:07 PM

got a hose end that’s 3/8-18 female npt. will this adapter let me hook it up to a 3/4-14 male npt port?

Answer by: Customer Support on Feb 16, 2026, 6:49 AM

It matches what you described. One side is a 3/8-18 Female NPT swivel, and the other side is a 3/4-14 Male NPT, straight.

Question by: Daryl W on Jul 13, 2025, 5:43 PM

got a 3/4 male NPT port on a manifold block and need to step down to a 3/8 female swivel connection. this the right fitting for that?

Answer by: Customer Support on Jul 15, 2025, 12:22 PM

That's what this adapter is built for. The male end threads into your 3/4-14 NPT port, and the 3/8-18 female NPT swivel end accepts the incoming line. The swivel feature on the female side makes it easier to get a clean, aligned connection without twisting up the hose or tubing during installation.

Question by: Ray C on May 14, 2025, 5:43 PM

Will this fitting work to adapt a 3/8" female pipe thread to a 3/4" male pipe thread?

Answer by: Customer Support on May 16, 2025, 6:48 AM

It adapts a 3/8-18 female NPT swivel to a 3/4-14 male NPT. So yes, that's the intended use.
