Question by: Earl M on Jul 24, 2025, 4:55 PM
got a 1/2 NPT female port and a 3/8 NPT female port that need to talk to each other, this the right piece for that?
Answer by: Customer Support on Jul 26, 2025, 8:39 AM
That's what this adapter is built for. One end is 1/2-14 female NPT and the other is 3/8-18 female NPT, so it bridges those two thread sizes in a straight, rigid connection. Steel construction keeps it solid under pressure, and since there's no thread sealant pre-applied, you can use whatever sealant or tape fits your setup.
