Merit Brass 01613-6440 Eccentric Reducer 4x2.5 in 316L Ss

Product Description

The MERIT BRASS 01613-6440 is a Schedule 10 eccentric reducer designed for pipe systems requiring an offset centerline transition between two pipe sizes. It steps down from 4 inches to 2-1/2 inches and connects via butt weld on both ends. Constructed from 316L stainless steel, this fitting offers reliable corrosion resistance in demanding fluid-handling applications. The eccentric profile keeps the bottom of the pipe flat, which is essential for drainage control and preventing air locks in horizontal runs. Licensed plumbers and pipe fitters are the primary installers of this fitting in process piping and mechanical systems.

This eccentric reducer is suited for residential and commercial plumbing, process piping, and industrial fluid-handling systems where a size transition is needed without shifting the pipe centerline symmetrically. The butt weld end connections make it appropriate for high-integrity, leak-resistant joints in welded stainless steel piping systems. Its 316L material grade makes it a common choice for corrosive media, chemical lines, food-service piping, and marine environments where standard stainless may fall short.

Key Features

• Eccentric design maintains a flat bottom for proper drainage in horizontal pipe runs
• 316L stainless steel construction provides enhanced corrosion resistance and low carbon content for weld integrity
• Butt weld x butt weld end connections for full-penetration, high-strength joints
• Schedule 10 wall thickness suitable for low-to-moderate pressure applications
• Steps down from 4 inches to 2-1/2 inches in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems sized at 4 x 2-1/2 inches.

Installation Notes

Installation requires a qualified pipe welder or licensed pipefitter using appropriate TIG or MIG welding equipment rated for 316L stainless steel. Purge the line and isolate all fluid or gas pressure before cutting into any existing piping. Follow ASME B16.9 standards for butt weld fittings and applicable local mechanical or plumbing codes. Do not apply open flame or heat to adjacent sections of pipe without appropriate heat shielding to prevent distortion of the fitting or adjacent components.
