Got a line running 3/4 NPTF male and need to drop it down to a 1/4 female NPTF port, this bushing do the trick?

Question by: Vince M on Jan 13, 2026, 6:50 AM

That's exactly what it's built for. The 5406-12-04 takes a 3/4-14 male NPTF thread on one end and steps it down to a 1/4-18 female NPTF on the other. Both threads meet SAE J476 spec, so you're getting a proper dry-seal fit on both sides, not just a standard pipe thread connection.

Question by: Daryl C on Aug 16, 2025, 2:27 PM

It reduces a 3/4-14 Male NPTF connection down to a 1/4-18 Female NPTF connection, so you can adapt a larger NPTF male thread into a smaller NPTF female thread size.
