Merit Brass 01606-4820 316L Ss Reducing Tee 3x1-1/4 in Sch 10

Product Description

The MERIT BRASS 01606-4820 is a 316L stainless steel reducing pipe tee designed for butt weld installation in Schedule 10 piping systems. It provides a 3-inch run with a 1-1/4-inch branch outlet, allowing a single fitting to redirect or split flow without additional reducers. The 316L low-carbon alloy delivers strong resistance to chloride corrosion and weld sensitization, making it a reliable choice in chemical processing, food service, marine, and industrial fluid handling applications. Licensed plumbers, pipefitters, and industrial pipe mechanics install this fitting in both new construction and retrofit work.

This reducing tee is suited for Schedule 10 stainless piping systems where a branch takeoff is required at a reduced diameter. Typical installations include process piping, sanitary lines, cooling water loops, and corrosive-fluid distribution systems. The butt weld end connections on all three outlets require socket or butt weld preparation and are joined by a qualified welder or certified pipefitter per applicable code requirements.

Key Features

• 316L low-carbon stainless steel resists weld sensitization and chloride-induced corrosion
• 3-inch run by 1-1/4-inch branch reducing configuration eliminates need for separate reducer fitting
• Butt weld end connections on all outlets for full-penetration, leak-tight joints
• Schedule 10 wall thickness suits low- to moderate-pressure fluid systems
• UNSPSC Code 40175300 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 10 stainless steel butt weld piping systems with a 3-inch main run and 1-1/4-inch branch outlet.

Installation Notes

Installation requires isolation of the piping system and full depressurization before cutting or fitting work begins. Butt weld connections must be made by a qualified welder following applicable codes such as ASME B31.3 or ASME B31.1 for process and pressure piping. Proper fit-up, alignment, and purging with an inert backing gas are standard practice for stainless steel weld joints to prevent oxidation. Do not use open-flame or grinding methods that could introduce carbon contamination into the 316L base material.
