Merit Brass 3414D-2404 Pipe Bushing 1-1/2 X 1/4 in Ss

Product Description

The MERIT BRASS 3414D-2404 is a threaded pipe bushing machined from 304/304L stainless steel, designed to reduce a 1-1/2 inch female NPT port down to a 1/4 inch male NPT connection. The external thread (MNPT) mates into a larger female-threaded fitting, while the internal thread (FNPT) accepts a smaller male-threaded pipe or fitting. Rated to 3,000 psi, this bushing suits high-pressure piping applications where corrosion resistance is a priority. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting when transitioning between pipe sizes within a threaded system.

This bushing is suited for use in industrial, commercial, and residential plumbing and piping systems where stainless steel is specified for corrosion resistance, sanitary requirements, or chemical compatibility. The 304/304L dual-grade material meets both standard and low-carbon stainless requirements, making it appropriate for welded assemblies or systems subject to intermittent high-temperature exposure. It is a direct drop-in reducer bushing wherever a 1-1/2 inch to 1/4 inch NPT reduction is needed in a threaded line.

Key Features

• 304/304L stainless steel construction for corrosion resistance and dual-grade material compliance
• 3,000 psi pressure rating suitable for high-pressure piping systems
• MNPT x FNPT threaded ends for tool-based installation without welding or crimping
• 1-1/2 inch to 1/4 inch size reduction in a single compact fitting
• Hex-body bushing design allows standard pipe wrench or hex wrench installation

Compatibility

Designed as an OEM-style threaded reducer bushing for use in 1-1/2 inch female NPT ports requiring a 1/4 inch male NPT outlet across threaded pipe assemblies in plumbing, hydraulic, and process piping applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and ASME B1.20.1 thread standards. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before makeup; do not overtighten, as stainless threads are susceptible to galling. Inspect thread engagement for at least three to five full turns before applying system pressure.
