Merit Brass 8040-300 Aluminum Pipe Nipple Sch 40 6061

Product Description

The MERIT BRASS 8040-300 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy, designed for low-pressure piping systems where corrosion resistance and light weight are priorities. Measuring 2.5 inches in diameter by 3 inches in length, it is threaded on both ends for direct connection to standard NPT fittings. Weighing 0.405 pounds, this nipple is well-suited for industrial, commercial, and mechanical piping applications where steel would add unnecessary mass or create galvanic concerns. Plumbers and pipefitters are the typical installers for this type of component.

This nipple fits into piping systems that require a short, threaded close-coupling section between two female NPT connections. The 6061 alloy grade offers good machinability and weld compatibility, making it a practical choice for fluid handling lines, pneumatic systems, and general mechanical piping where aluminum is the specified material. Schedule 40 wall thickness meets standard pressure and flow requirements for this diameter in typical service conditions.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and reduced weight
• Schedule 40 wall thickness for standard-duty piping service
• Threaded on both ends for NPT-compatible installation
• 2.5-inch nominal diameter by 3-inch length for close-coupling applications
• Lightweight at 0.405 pounds, reducing load in multi-fitting assemblies

Compatibility

Designed as an OEM-style replacement or direct-install component for Schedule 40 aluminum piping systems using standard NPT threaded connections at 2.5-inch nominal diameter.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or ASME B31 piping codes. Depressurize and drain the line completely before removing or installing any threaded nipple. Apply a thread sealant rated for aluminum and the conveyed fluid before making up connections. Do not over-torque aluminum threads, as the material is softer than steel and susceptible to thread damage under excessive force.
