Merit 04412-4016 Concentric Reducing Coupling 2.5x1in Sch 40

Product Description

The MERIT 04412-4016 is a concentric reducing coupling designed for butt weld installation in stainless steel piping systems. Manufactured from 304/304L stainless steel, it provides corrosion resistance suited to demanding process, industrial, and mechanical piping applications. The fitting transitions from a 2-1/2 inch nominal pipe to a 1 inch nominal pipe along a shared centerline, maintaining flow alignment through the reduction. At 3-1/2 inches in length and rated for SCH 40/STD schedule pipe, it is sized for standard wall butt weld connections. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers of this type of fitting.

This concentric reducing coupling is suited for use in process piping, sanitary systems, chemical handling lines, and industrial fluid systems where stainless steel construction and butt weld joints are specified. The concentric design keeps inlet and outlet centerlines aligned, which is preferred in horizontal runs where consistent flow path geometry matters. It is appropriate for both residential and commercial mechanical systems that call for SCH 40/STD stainless steel butt weld fittings at this nominal size transition.

Key Features

• Concentric reducing design maintains shared centerline between 2-1/2 inch and 1 inch nominal pipe ends
• 304/304L dual-grade stainless steel construction provides corrosion resistance in wet and chemical environments
• Butt weld end style for full-penetration welded joints with flush inner diameter
• SCH 40/STD schedule rating compatible with standard wall stainless steel pipe
• 3-1/2 inch overall length suits standard butt weld fitup spacing
• Lightweight at 0.63 pounds for easy handling during fitup and tacking

Compatibility

Designed as an OEM-style replacement and new-installation fitting for SCH 40/STD stainless steel butt weld piping systems transitioning from 2-1/2 inch to 1 inch nominal pipe diameter.

Installation Notes

Installation is performed by a qualified pipefitter or licensed plumber following applicable codes such as ASME B31.3 for process piping or the International Plumbing Code for mechanical systems. Depressurize and isolate the line completely before cutting in the fitting. Butt weld fittings require proper beveling, alignment, and purge welding practices for full-penetration joints on stainless steel pipe. Post-weld passivation or pickling may be required depending on system service conditions.
