Got a 3/4 male NPT port on a manifold block and need to step it up to a 1-inch female connection. This the right part for that job?
Question by: Ray B on Jun 17, 2025, 7:23 AM
That's what this adapter is built for. It takes a 3/4-14 male NPT thread on one end and accepts a 1-11-1/2 female NPT connection on the other, all in a straight configuration. It's part of the Eaton Aeroquip 2040 Series, so the thread dimensions and countersunk hex body are consistent with that lineup. For stepping up thread sizes between those two specific NPT sizes in a straight run, this is the correct fit.

Is this the right fitting to go from a 3/4 inch male NPT to a 1 inch female NPT?
Question by: Jean W on Feb 17, 2026, 12:32 PM
That's exactly right. This adapter features a 3/4-14 male NPT thread on one end and a 1-11-1/2 female NPT thread on the other, making it a straight adapter for that conversion.
