Merit Brass 8008-400 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8008-400 is a 6061 aluminum pipe nipple designed for threaded piping assemblies in plumbing, industrial, and mechanical systems. Machined to Schedule 40 wall thickness, this nipple measures 1/2 inch nominal pipe size and 4 inches in length, with threads on both ends for direct connection between fittings or into threaded ports. At 0.12 pounds, it is lightweight without sacrificing the structural integrity expected in a Schedule 40 fitting. Licensed plumbers and pipefitters install this nipple as a standard connecting element wherever aluminum piping is specified.

This nipple is suited for residential and commercial piping applications where aluminum construction is preferred over steel or brass — typically in compressed air lines, low-pressure fluid systems, and OSHA-regulated installations. Its 6061 alloy construction offers good corrosion resistance and machinability, making it a practical choice for fabricated assemblies and retrofit work in mechanical rooms and utility spaces.

Key Features

• 6061 aluminum construction for corrosion resistance and light weight
• Schedule 40 wall thickness for pressure-rated piping assemblies
• Threaded on both ends for standard NPT connections
• 1/2 inch nominal pipe size x 4 inches overall length
• Meets OSHA standards
• Lightweight at 0.12 pounds — reduces load in overhead or rack-mounted runs

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2 inch NPT threaded plumbing and piping systems specifying Schedule 40 aluminum pipe nipples.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off the fluid or air supply and depressurize the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape appropriate for the service medium before making up the connection. Avoid over-tightening, which can crack aluminum threads; follow applicable IPC or IFGC guidelines for fitting makeup on aluminum piping.
