Merit Brass 04412-4820 Concentric Reducer 3x1-1/4 in 304L Ss

Product Description

The MERIT BRASS 04412-4820 is a concentric reducer pipe fitting designed for butt weld installation in Schedule 40 piping systems. It transitions flow from a 3-inch pipe down to a 1-1/4-inch pipe along a centered axis, maintaining flow symmetry through the reduction. Constructed from 304L stainless steel, this fitting offers reliable corrosion resistance in a wide range of fluid-handling applications. The butt weld end connections require full-penetration welds on both ends, making this a permanent, high-integrity joint suitable for pressure piping. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this component.

This concentric reducer is suited for use in residential, commercial, and light industrial piping systems where a Schedule 40 stainless steel butt weld fitting is required. Typical applications include process piping, utility water lines, HVAC hydronic systems, and food-grade or sanitary-adjacent installations where 304L stainless steel meets the corrosion-resistance requirements of the service environment. The fitting is sold individually and ships as a single unit.

Key Features

• 304L low-carbon stainless steel construction for weld-friendly corrosion-resistant performance
• Concentric design keeps pipe centerlines aligned through the reduction
• Butt weld x butt weld end connections for full-penetration, permanent joints
• Schedule 40 wall thickness compatible with standard Schedule 40 pipe
• 3-inch to 1-1/4-inch reduction covers a significant flow transition in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 stainless steel butt weld piping systems requiring a 3-inch by 1-1/4-inch concentric reduction.

Installation Notes

Installation requires a certified welder or licensed pipefitter using appropriate TIG or MIG welding procedures for 304L stainless steel. Shut down and depressurize the piping system completely before cutting into any existing line. Follow applicable codes including ASME B16.9 for factory-made wrought butt-welding fittings and any local mechanical or plumbing codes governing the installation. Post-weld cleaning or passivation may be required depending on the service environment.
