Merit Brass 01613-8064 Eccentric Reducer 5x4 in 316L Ss Butt Weld

Product Description

The MERIT BRASS 01613-8064 is a 5 x 4 inch eccentric reducer fitting manufactured from 316L stainless steel. It connects two different pipe diameters while maintaining a flat bottom alignment, which prevents air or gas pockets from forming in liquid lines. The butt weld end connections on both ends provide a full-penetration joint suited for high-purity and corrosion-resistant piping systems. Built to Schedule 10 wall thickness, this fitting is used in process piping, sanitary systems, and industrial fluid handling where 316L stainless steel is specified for its low carbon content and resistance to intergranular corrosion. Installation is performed by qualified pipe welders or licensed pipefitters.

This eccentric reducer is intended for use in commercial and industrial piping systems where transitions from 5 inch to 4 inch pipe diameter are required. The eccentric profile keeps one side of the pipe run flat, making it the preferred choice for pump suction lines and horizontal runs where drainage and air elimination are critical. Applications include process piping, chemical transfer lines, food and beverage facilities, and marine or coastal installations where 316L stainless steel offers superior corrosion resistance over standard 304 grades.

Key Features

• 316L stainless steel construction provides low carbon content and strong resistance to intergranular corrosion after welding
• Eccentric design maintains flat-bottom alignment to prevent air entrapment in liquid piping systems
• Butt weld x butt weld end connections on both ends for full-penetration, high-integrity joints
• Schedule 10 wall thickness suited for low- to medium-pressure industrial and process piping
• 5 x 4 inch fitting size accommodates common large-diameter pipe transitions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems requiring a 5 x 4 inch eccentric reduction.

Installation Notes

Installation requires a certified pipe welder following applicable welding procedures for 316L stainless steel, typically per ASME B31.3 or B31.1 process and power piping codes. Isolate and depressurize the piping system fully before cutting into any existing line. Purge the interior of stainless steel fittings with inert gas during welding to prevent oxidation on the weld root. Do not use carbon steel tools or wire brushes on stainless steel surfaces, as contamination can initiate corrosion.
