Merit Brass 01413-6424 Eccentric Reducer 4x1.5 in 304L Ss

Product Description

The MERIT BRASS 01413-6424 is a Schedule 10 eccentric reducer fitting used to connect pipe runs of different diameters while maintaining a flat side on the pipe centerline. Constructed from 304L stainless steel, this fitting is suited for corrosion-resistant piping systems in commercial and industrial applications. The 4 inch by 1.5 inch eccentric profile allows for controlled flow transition and prevents air pockets in horizontal liquid lines. Both ends are butt weld connection type, requiring orbital or manual weld joining by a qualified pipefitter or welder. At 0.75 pounds, the fitting is lightweight for its size and easy to handle during installation.

This eccentric reducer is appropriate for use in process piping, plumbing, and mechanical systems where stainless steel construction is specified. Schedule 10 wall thickness makes it suitable for moderate-pressure service in sanitary, food-grade, chemical, or general industrial piping. It is commonly installed in horizontal pipe runs where maintaining a level bottom is required to allow proper drainage or to prevent trapped air. Qualified pipefitters and welders working under applicable codes typically install this type of fitting in both new construction and retrofit piping systems.

Key Features

• Eccentric profile keeps one side of the pipe flat, preventing air lock in horizontal liquid lines
• 304L stainless steel construction provides low carbon content for improved weld corrosion resistance
• Butt weld end connections on both ends for full-penetration welded joints
• Schedule 10 wall thickness for moderate-pressure service
• Reduces from 4 inches to 1.5 inches for transitioning between mismatched pipe sizes
• Lightweight at 0.75 pounds for easier handling during fit-up

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems requiring a 4 inch by 1.5 inch eccentric reduction.

Installation Notes

Installation should be performed by a qualified pipefitter or certified welder in accordance with applicable mechanical and piping codes. Isolate and depressurize the pipe system completely before cutting in or removing any existing fitting. Butt weld joints require proper fit-up, cleaning, and shielding gas or backing as appropriate for the weld process used on 304L stainless steel. Follow applicable codes such as ASME B31.3 for process piping or the International Plumbing Code for plumbing applications.
