Question by: Neal L on May 3, 2025, 5:22 PM
got a line with a 3/8-18 female npt port and the valve side is 1/4-18 female npt. is this the straight adapter that bridges those two?
Answer by: Customer Support on May 4, 2025, 8:36 PM
Made for pipe-to-pipe connections, it couples a 3/8-18 female NPT thread on one end to a 1/4-18 female NPT thread on the other in a straight, rigid union style.
Question by: Kurt D on Oct 27, 2025, 10:16 AM
Got a line running 3/8 female NPT and need to step it down to 1/4 female NPT without a bunch of fittings in between. This the right piece for that?
Answer by: Customer Support on Oct 28, 2025, 3:22 PM
That's what this adapter is built for. One end threads into a 3/8-18 female NPT connection, the other picks up a 1/4-18 female NPT, and it does it all in a straight, compact form. No extra couplings needed in between.
Question by: Hank R on Nov 13, 2025, 4:04 PM
What size threads does this adapter have? Just wanna make sure it'll fit my setup.
Answer by: Customer Support on Nov 15, 2025, 8:22 AM
It comes with 3/8-18 female NPT on one end and 1/4-18 female NPT on the other, which is handy for connecting different sized pipes without needing sealant.
