Merit Brass SW3412D-1604 Pipe Reducer 1x1/4 Ss Socket Weld

Product Description

The MERIT BRASS SW3412D-1604 is a socket weld pipe reducer fitting designed to transition pipe from a 1-inch nominal size down to a 1/4-inch nominal size. Constructed from 304 stainless steel, this fitting is rated for service up to 3,000 psi, making it suitable for demanding high-pressure fluid and gas piping systems. The socket weld end connections on both sides allow the fitting to be welded directly onto pipe ends, creating a strong, leak-resistant joint. Licensed plumbers, pipefitters, and industrial tradespeople install this fitting in systems where a permanent, high-integrity connection is required.

This reducer is commonly used in commercial and industrial piping installations, including process piping, hydraulic lines, steam systems, and other high-pressure applications where a reduction in line size is needed. The 304 stainless steel construction provides solid corrosion resistance for use with water, steam, mild chemicals, and other compatible media. It is well suited for both new construction and retrofit work in industrial facilities, mechanical rooms, and process plants.

Key Features

• Socket weld connections on both ends for a permanent, welded joint
• Reduces from 1-inch nominal pipe to 1/4-inch nominal pipe in a single fitting
• Sold individually — package quantity of one

Compatibility

Designed as an OEM-style replacement or new-installation fitting for high-pressure socket weld piping systems using 1-inch to 1/4-inch nominal pipe sizes.

Installation Notes

Socket weld fittings are installed by licensed pipefitters or plumbers qualified in welding procedures applicable to stainless steel pipe. Isolate and fully depressurize the piping system and allow it to cool before cutting into any existing line. Follow applicable codes including ASME B31.1 or B31.3 for process piping when selecting weld procedures, filler materials, and inspection requirements. Do not use this fitting in services or pressure ratings beyond those specified without verifying suitability with a qualified engineer.
