what's the actual outside diameter on a 3/8 standard pipe nipple? trying to figure out if it'll thread into a fitting i already got on hand

Question by: Carl R on Jan 24, 2026, 3:40 PM

Standard pipe sizing runs a little counterintuitive if you haven't dealt with it much. A 3/8 NPT pipe nipple has an outside diameter of roughly 0.675 inches on the threaded portion. The "3/8" refers to the nominal pipe size, not the actual measured diameter, so don't let that trip you up when you're checking your existing fitting threads.

Just want to make sure this'll fit a standard 3/8" threaded pipe?

Yes, this is a standard 3/8" black steel pipe nipple with threads on both ends, so it should fit any standard 3/8" threaded connection.
