Merit Brass 01406-4816 Stainless Steel Pipe Tee 3x1 in

Product Description

The MERIT BRASS 01406-4816 is a Schedule 10 reducing pipe tee fabricated from 304L stainless steel, designed for butt weld installation in industrial and commercial piping systems. The tee connects a 3-inch run pipe to a 1-inch branch outlet, making it a standard reducing configuration for flow diversion or branch takeoff applications. The 304L grade designation indicates low-carbon austenitic stainless steel, which offers good corrosion resistance and is well suited for welded assemblies where intergranular corrosion is a concern. Licensed plumbers, pipefitters, and industrial pipe welders are the primary installers of this fitting type.

This fitting is used in Schedule 10 stainless steel piping systems found in commercial plumbing, food processing, pharmaceutical, and light industrial process piping. The butt weld end connection on both the run and branch outlets requires proper fit-up and fusion welding, making it appropriate for permanent, leak-tight installations where mechanical couplings are not preferred. The 3 x 1 inch size combination suits applications where a main line must feed a smaller branch line without a full-size outlet.

Key Features

• 304L low-carbon stainless steel construction resists corrosion in wet and chemical environments
• Butt weld end connections on run and branch for permanent, high-integrity joints
• Schedule 10 wall thickness compatible with Schedule 10 stainless pipe systems
• Reducing configuration: 3-inch run by 1-inch branch outlet
• UNSPSC Code 40175300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems requiring a 3 x 1 inch reducing tee configuration.

Installation Notes

This fitting is installed by qualified pipefitters or welders trained in stainless steel butt weld procedures. Purge the line and depressurize the system completely before cutting into any existing piping. Proper fit-up, back purging with inert gas, and weld procedure compliance are critical when welding 304L stainless to prevent contamination and maintain corrosion resistance. Refer to applicable codes such as ASME B31.3 for process piping or ASME B31.1 for power piping when determining weld qualification requirements.
