Merit Brass 01613-2012 Eccentric Reducer 316L Ss Butt Weld

Product Description

The MERIT BRASS 01613-2012 is a Schedule 10 eccentric reducer fitting designed for pipe transition from 1-1/4 inch to 3/4 inch nominal diameter. Constructed from 316L stainless steel, this fitting is suited for corrosion-resistant piping systems where weld integrity and material consistency are critical. Both ends feature butt weld connections, making it appropriate for permanent, high-integrity piping assemblies. Licensed pipefitters and plumbers install this type of fitting in process, industrial, and commercial applications where off-center bore alignment is required to maintain a flat bottom or top reference plane in the pipeline.

Eccentric reducers are commonly used in liquid service lines where air pocket prevention or consistent drainage slope is necessary. The flat-side geometry of an eccentric reducer allows the pipe invert or crown to remain level across the transition, which matters in pump suction lines, gravity drain configurations, and sloped process piping. This fitting is appropriate for residential, commercial, and light industrial piping systems built to Schedule 10 stainless steel specifications.

Key Features

• 316L stainless steel construction provides superior chloride and corrosion resistance compared to standard 304-grade fittings
• Eccentric bore geometry maintains flat-bottom or flat-top alignment across the pipe size transition
• Butt weld end connections on both ends allow full-penetration welds for leak-tight, permanent joints
• Schedule 10 wall rating suitable for low-to-medium pressure stainless piping systems
• Compact and lightweight at 0.13 pounds, minimizing load on adjacent pipe supports

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems transitioning from 1-1/4 inch to 3/4 inch nominal pipe size.

Installation Notes

Installation requires a qualified pipefitter or welder certified for stainless steel TIG or plasma butt weld procedures. Thoroughly purge and clean both mating pipe ends before fitup to prevent weld contamination. Isolate and depressurize the piping system completely before cutting in or replacing any reducer fitting. All weld procedures on pressure piping should comply with applicable codes such as ASME B31.3 or B31.1 as required by the system classification.
