Merit Brass SW3412D-1204 Pipe Reducer 3/4 X 1/4 in Socket Weld

Product Description

The MERIT BRASS SW3412D-1204 is a socket weld pipe reducer designed to transition flow lines from a 3/4-inch pipe to a 1/4-inch pipe in high-pressure piping systems. Constructed from 304 stainless steel, this fitting carries a 3,000 psi pressure rating, making it suited for demanding process, industrial, and mechanical applications. The socket weld end connections require field welding by a qualified welder, producing a permanent, leak-resistant joint appropriate for systems where threaded connections are not acceptable. Plumbers, pipefitters, and mechanical contractors working on stainless steel process lines or utility piping will typically install this fitting.

This reducer is used in residential, commercial, and light industrial piping systems where line size must be reduced between two socket weld pipe sections. Typical applications include instrument tubing connections, compressed air lines, hydraulic supply lines, and chemical process piping where 304 stainless steel corrosion resistance is required. The fitting is sold individually, making it straightforward to source as a single replacement or addition to an existing system.

Key Features

• 304 stainless steel construction provides corrosion resistance in wet and chemical environments
• 3,000 psi pressure rating suits high-pressure piping service
• Socket weld x socket weld end connections on both ends for permanent welded joints
• Reduces line size from 3/4 inch to 1/4 inch in a single fitting
• Sold as individual unit with no minimum order beyond one piece

Compatibility

Designed as an OEM-style socket weld reducer for standard 3/4-inch by 1/4-inch stainless steel pipe configurations rated to 3,000 psi service.

Installation Notes

Installation requires a certified welder following applicable codes such as ASME B31.1 or B31.3 for process and power piping. Isolate and fully depressurize the line before cutting in or replacing any fitting. Verify pipe end preparation and socket depth to ASME B16.11 standards prior to welding. Do not use thread sealants or mechanical connection methods on socket weld ends.
