Merit Brass 3412D-2408 Pipe Reducer 1-1/2x1/2 in Fnpt 3000 Psi

Product Description

The MERIT BRASS 3412D-2408 is a threaded pipe reducer fitting manufactured from 304/304L stainless steel. It transitions from a 1-1/2 inch female NPT connection to a 1/2 inch female NPT connection, making it suitable for reducing pipe diameter within pressurized fluid or gas systems. Rated to 3,000 psi, this reducer handles high-pressure service conditions common in industrial, mechanical, and plumbing applications. The dual-grade 304/304L stainless steel construction provides corrosion resistance across a wide range of process environments. Plumbers, pipefitters, and mechanical contractors typically install this fitting in threaded piping assemblies where a direct inline reduction is required.

This reducer is suited for residential and commercial piping systems where a threaded inline reduction from 1-1/2 inch to 1/2 inch pipe is needed. Typical applications include process piping, water supply systems, compressed air lines, and hydraulic distribution networks. The FNPT x FNPT end connections allow straightforward integration into standard NPT threaded piping runs without the need for welding or special tooling. Its 3,000 psi pressure rating makes it appropriate for higher-pressure service lines beyond standard residential water supply.

Key Features

• 304/304L dual-grade stainless steel construction for corrosion resistance in wet and process environments
• 3,000 psi pressure rating suitable for high-pressure piping applications
• FNPT x FNPT threaded end connections for tool-only installation with no welding required
• Inline reducer configuration transitions 1-1/2 inch pipe down to 1/2 inch pipe
• Compact threaded fitting design integrates directly into standard NPT piping systems

Compatibility

Designed as an OEM-style threaded pipe reducer compatible with standard NPT piping systems requiring an inline 1-1/2 inch to 1/2 inch female-to-female reduction in 304/304L stainless steel.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical codes. Depressurize and drain the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male NPT threads mating into this fitting per the manufacturer and code requirements. Do not overtighten threaded stainless steel fittings, as galling of the threads can occur; use proper pipe wrenches and follow standard torque practices for NPT connections.
