Merit Brass 4006-6000 Stainless Steel Pipe Nipple 3/8 in Sch 40

Product Description

The MERIT BRASS 4006-6000 is a welded stainless steel pipe nipple sized for 3/8 inch pipe, manufactured to Schedule 40 wall thickness from Grade 304/304L stainless steel. It serves as a short threaded connector in piping systems where corrosion resistance and strength are required. Licensed plumbers, HVAC technicians, and pipefitters install this nipple to join or extend threaded pipe runs in fluid and gas distribution systems. The 304/304L dual-certified material grade accommodates both standard and low-carbon stainless requirements, making it suitable for welded or threaded fabrication environments where heat-affected zones may be a concern.

This pipe nipple is used in residential and commercial plumbing, HVAC hydronic piping, compressed air distribution, and light industrial process piping. Schedule 40 sizing ensures compatibility with standard NPT fittings and valves commonly found in these applications. It is particularly well-suited for installations in wet or corrosive environments where carbon steel fittings would be prone to rust or chemical attack, such as coastal HVAC systems, water treatment equipment, and food-service plumbing rough-in work.

Key Features

• Grade 304/304L dual-certified stainless steel construction for corrosion resistance in wet and chemical environments
• Welded construction meets Schedule 40 wall thickness requirements for standard 3/8 inch pipe
• Threaded ends compatible with standard NPT fittings, valves, and couplings
• Low-carbon 304L designation provides compatibility with welded fabrication applications
• UNSPSC Code 40173300 for procurement and classification compliance

Compatibility

Designed as an OEM-style replacement and standard-stock fitting for 3/8 inch Schedule 40 NPT threaded piping systems in plumbing, HVAC, and light industrial applications.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC and local plumbing code requirements. Shut off and depressurize the system fully before removing or installing any threaded pipe fitting. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not over-torque threaded connections on stainless fittings, as galling can occur between stainless mating surfaces.
