Merit Brass 4006-800 Stainless Steel Pipe Nipple 3/8 in Sch 40

Product Description

The MERIT BRASS 4006-800 is a 3/8-inch stainless steel pipe nipple constructed from Grade 304/304L stainless steel using a welded process to Schedule 40 wall thickness. It is designed for use in fluid and gas piping systems where corrosion resistance and mechanical strength are required. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting when connecting threaded pipe runs in commercial and industrial applications. The Schedule 40 wall rating and 304/304L material grade make it suitable for moderate-pressure service in a range of process and utility piping environments.

This nipple fits into residential and commercial piping systems that require a compact, threaded stainless connector. Typical applications include water supply lines, steam systems, chemical lines, and HVAC condensate or refrigerant piping where corrosion resistance is a priority. It is suited for indoor and outdoor installations where carbon steel fittings would be prone to rust or contamination. The 3/8-inch thread size is common in utility branch lines and instrument connections throughout mechanical and process systems.

Key Features

• Grade 304/304L stainless steel construction provides corrosion resistance in wet and chemical-exposure environments
• Welded construction meets Schedule 40 wall thickness standards for moderate-pressure service
• 3/8-inch pipe size with matching 3/8-inch thread size for direct connection to standard NPT fittings
• Compact nipple form factor allows close-coupled connections in tight spaces
• UNSPSC Code 40173300 for procurement and catalog alignment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8-inch NPT threaded pipe systems using Schedule 40 stainless steel components.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and ASME B31 piping codes. Shut off and depressurize the system before removing or installing any threaded fitting. Apply an appropriate thread sealant rated for stainless steel and the intended service medium. Do not over-torque threaded connections, as this can stress welded stainless nipples and compromise the joint.
