got a 3/8 male npt port on a block, but my gauge line is 1/4 npt. is this the right bushing to step it down
Answer by: Customer Support on Aug 3, 2025, 7:30 PM
For that setup, yes. It is a bushing-style adapter that threads a 3/8 inch male NPT end into your 3/8 NPT port and gives you a 1/4 inch female NPT port to screw your 1/4 NPT fitting or gauge into.

Yes, this adapter bushing is designed to provide a reliable connection between a 1/4-inch female NPT port and a 3/8-inch male NPT port.
