Question by: Keith T on Nov 21, 2025, 8:16 AM
got a 3/8-18 npt port but my gauge line is 1/8-27 npt. is this the right little bushing to step it down
Answer by: Customer Support on Nov 22, 2025, 2:01 PM
For stepping a 3/8-18 male NPT connection down to a 1/8-27 female NPT connection, this bushing is the correct thread match. It is a pipe-to-pipe adapter meant to join two different NPT sizes when you need a reduction.
