Merit Brass 4006-2400 Stainless Steel Pipe Nipple 3/8 in Sch 40

Product Description

The MERIT BRASS 4006-2400 is a welded stainless steel pipe nipple designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Sized for 3/8-inch pipe at Schedule 40 wall thickness, it is manufactured from Grade 304/304L stainless steel, which provides good corrosion resistance in a wide range of service environments. This nipple is a standard close or short-run connector used to join threaded fittings, valves, and equipment in both new installations and repair work. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers of this component.

This pipe nipple is suited for residential and light commercial applications where a 3/8-inch threaded connection is required. Common uses include connecting valves, gauges, sensors, or branch lines in water, steam, air, and compatible fluid service systems. The 304/304L dual-grade designation makes it usable in both standard and low-carbon weld-affected applications. Schedule 40 wall thickness meets typical pressure requirements for these service categories.

Key Features

• Grade 304/304L stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• Welded construction meeting Schedule 40 wall thickness requirements
• 3/8-inch pipe size with standard NPT-compatible threaded ends
• Dual-grade 304/304L designation supports use in weld-adjacent piping configurations
• UNSPSC Code 40173300 for procurement and cataloging systems

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/8-inch threaded pipe systems requiring Schedule 40 stainless steel nipples.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service medium. Always depressurize and isolate the line section before removing or installing threaded nipples. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten threaded stainless fittings, as galling of the threads can occur.
