Service Metal ser0401.5 Eccentric Reducer 4x1.5 in Carbon Steel

Product Description

The SERVICE METAL ser0401.5 is a standard eccentric reducer fitting used in carbon steel butt weld piping systems. It transitions pipe diameter from 4 inches down to 1.5 inches while maintaining a flat side along one axis, which is the defining characteristic of an eccentric reducer. Weighing 3 pounds, this import fitting is built to standard dimensional tolerances for butt weld end connections. It is installed by certified pipefitters, plumbers, and mechanical contractors working on commercial or industrial piping systems where flow control, drainage slope, or pump alignment requires an offset centerline reduction.

This eccentric reducer is suited for commercial and industrial piping applications where controlling the bottom-of-pipe elevation is critical, such as pump suction lines, horizontal drains, and process piping layouts. The eccentric geometry prevents air pockets from forming in liquid lines and keeps the pipe bottom level when installed correctly. It fits standard 4 inch to 1.5 inch butt weld piping configurations found in mechanical rooms, process facilities, and large commercial HVAC hydronic systems.

Key Features

• Eccentric design maintains flat-side alignment to prevent air entrainment in liquid piping systems
• Carbon steel construction for use in high-pressure and high-temperature piping applications
• Butt weld end connections for full-penetration welds and strong, leak-resistant joints
• Standard wall designation compatible with common schedule butt weld fittings
• 4 inch inlet to 1.5 inch outlet transition for significant diameter reduction in a single fitting

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard carbon steel butt weld piping systems requiring a 4 inch by 1.5 inch eccentric reduction.

Installation Notes

Installation requires a qualified welder or certified pipefitter following applicable welding procedures and mechanical codes. Depressurize and drain the piping system completely before cutting in or replacing any fitting. Butt weld fittings require proper fit-up, tacking, and full-penetration welds inspected per the applicable piping specification. Orient the flat side up or down based on the system requirement — flat side up for gas or vapor lines, flat side down for liquid pump suction and drain applications.
