Merit Brass 01413-2016 Eccentric Reducer 1-1/4x1 304L Ss Butt Weld

Product Description

The MERIT BRASS 01413-2016 is a Schedule 10 eccentric reducer designed for butt weld pipe connections transitioning from 1-1/4 inch to 1 inch nominal pipe size. Constructed from 304L stainless steel, this fitting delivers reliable corrosion resistance in demanding piping systems. The eccentric geometry offsets the pipe centerlines, keeping the bottom of the pipe run flat — a critical feature when managing drainage slope or avoiding air pockets in horizontal runs. At 0.32 pounds, the fitting is lightweight without sacrificing structural integrity. It is typically installed by licensed plumbers, pipefitters, or mechanical contractors working on process, industrial, or commercial piping systems.

This eccentric reducer is suited for use in stainless steel piping systems where maintaining a consistent bottom-of-pipe elevation is necessary. Common applications include process piping, sanitary systems, HVAC hydronic lines, and light industrial fluid handling. The butt weld end connections require proper pipe preparation and welding procedures, making this fitting appropriate for professional installation in systems where leak-free, permanent joints are required.

Key Features

• Eccentric design keeps bottom of pipe flat, preventing air traps and aiding drainage in horizontal runs
• 304L stainless steel construction provides strong corrosion resistance for process and industrial environments
• Schedule 10 wall thickness suitable for low- to medium-pressure piping applications
• Butt weld x butt weld end connections for permanent, full-penetration welded joints
• Transitions 1-1/4 inch nominal pipe down to 1 inch nominal pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems using 1-1/4 inch to 1 inch nominal pipe sizes.

Installation Notes

Installation should be performed by a qualified pipefitter or welder familiar with stainless steel butt weld procedures. Depressurize and drain the system fully before cutting into any existing pipe run. Follow applicable codes including ASME B31.3 or B31.9 for process and building mechanical piping. Avoid introducing contaminants into the weld zone — clean pipe ends and maintain proper fit-up before welding.
