24MP-04FP REDUCER BUSHING

Description & Features

Built from straight steel construction, the 24MP-04FP Reducer Bushing steps down a 1-1/2-11-1/2 Male Nptf thread to a 1/4-18 Female Nptf connection, both conforming to SAE J476. This significant size reduction makes it well-suited for hydraulic lines requiring a transition between mismatched thread sizes without additional fittings.

Rated to 3,000 PSI maximum dynamic pressure, this fitting is appropriate for moderate- to high-pressure hydraulic circuits. Part of Brennan Industries' 5406 Series, it measures 1.570 mm in overall length and is manufactured to consistent dimensional standards across the series.

Question by: Joyce A on Mar 1, 2026, 6:41 AM

Hey, just want to make sure this reducer bushing will fit my setup. I got a 1-1/2 NPT fitting and need to go down to 1/4 NPT.

Answer by: Customer Support on Mar 2, 2026, 1:12 PM

For hydraulic lines needing that specific transition, this reducer bushing will work. It's designed to step down from a 1-1/2-11-1/2 Male NPTF thread to a 1/4-18 Female NPTF connection, according to SAE J476 standards.
