Merit Brass 01426-20 Pipe Stud End 1-1/4 in 304L Ss Butt Weld

Product Description

The MERIT BRASS 01426-20 is a 1-1/4 inch pipe stud end fitting manufactured from 304L stainless steel and designed for butt weld connections on Schedule 10 piping systems. Stud ends serve as the weld-neck or lap-joint interface that accepts a loose flange, allowing rotational alignment during bolted assembly. The 304L alloy designation indicates a low-carbon austenitic grade well suited for corrosion-resistant process, mechanical, and fluid-handling installations. This fitting is typically installed by licensed plumbers, pipefitters, or mechanical contractors working on light-wall stainless piping runs.

This stud end fitting is appropriate for residential and commercial mechanical systems that require a butt weld termination point at a flanged connection. Typical applications include process piping, chemical handling lines, sanitary installations, and general-purpose stainless plumbing assemblies where Schedule 10 wall thickness meets the flow and pressure demands of the system. Its butt weld by butt weld end connection suits fabricated spool assemblies that are welded off-site and then flanged into service at the job.

Key Features

• 304L low-carbon stainless steel construction resists corrosion in wet and chemically active environments
• Butt weld by butt weld end connections for full-penetration welded joints
• Schedule 10 wall thickness for light-wall piping applications
• 1-1/4 inch fitting size for standard nominal pipe sizing
• 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 using 1-1/4 inch nominal pipe size.

Installation Notes

Installation should be performed by a qualified pipefitter or licensed plumber familiar with stainless steel butt welding procedures. Shut down and depressurize the piping system fully before cutting into any existing line. Butt weld joints must be completed to applicable welding codes such as ASME B31.3 for process piping or the applicable local mechanical code. Do not over-grind or overheat the weld zone, as excessive heat input can reduce corrosion resistance in the heat-affected zone of low-carbon grades.
