Merit Brass 01613-2016 Eccentric Reducer 1-1/4x1 316L Ss

Product Description

The MERIT BRASS 01613-2016 is a Schedule 10 eccentric reducer fitting designed for butt weld installation in stainless steel piping systems. Constructed from 316L stainless steel, this fitting transitions pipe diameter from 1-1/4 inches to 1 inch while maintaining an offset centerline -- the defining characteristic of an eccentric reducer. That flat-side geometry allows the fitting to sit flush against a surface or rack, which is critical for liquid drainage and pump inlet piping where air pockets must be avoided. Weighing 0.38 pounds, it is a lightweight but corrosion-resistant component suited for demanding service environments. Licensed pipefitters and plumbing contractors are the typical installers for this type of fitting.

This eccentric reducer is well suited for process piping, industrial fluid systems, food-grade or sanitary-adjacent applications, and any installation where 316L stainless steel is specified for corrosion resistance or code compliance. Schedule 10 wall thickness makes it appropriate for moderate-pressure systems where full-bore flow capacity and reduced weight are priorities. Both ends accept standard butt weld connections, integrating cleanly into all-welded piping systems without threaded or mechanical joint transitions.

Key Features

• 316L stainless steel construction provides excellent resistance to corrosion, chlorides, and oxidation
• Eccentric offset centerline prevents air entrainment at pump inlets and supports complete liquid drainage
• Butt weld end connections on both ends for fully welded, leak-resistant piping assemblies
• Schedule 10 wall thickness balances flow capacity with reduced system weight
• 1-1/4 inch to 1 inch size transition handles common pipe reduction requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems requiring a 1-1/4 inch to 1 inch eccentric reduction.

Installation Notes

Butt weld fittings must be installed by a qualified welder or licensed pipefitter in accordance with applicable codes such as ASME B31.3 or ASME B31.1 for process and power piping. Depressurize and drain the system fully before cutting into any existing piping. Proper fit-up, tack welding, and full-penetration welds are required to maintain pressure integrity and meet inspection standards. On pump suction lines, orient the flat side of the eccentric reducer upward to prevent air lock.
