Merit Brass 8064-400 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8064-400 is a 4 inch x 4 inch Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy and threaded on both ends. It is designed for use in piping systems where corrosion resistance and light weight are priorities over ferrous fittings. The 6061 alloy designation indicates a heat-treatable, medium-strength aluminum suitable for a broad range of industrial and mechanical piping applications. This nipple is OSHA-compliant and is typically installed by licensed plumbers, pipefitters, or industrial maintenance technicians working on fluid or air distribution systems.

This pipe nipple is suited for residential, commercial, and light industrial applications where aluminum piping is specified. Common install scenarios include compressed air lines, irrigation headers, chemical transfer systems where mild corrosion resistance is required, and other low-to-moderate pressure fluid systems. The Schedule 40 wall thickness meets standard dimensional requirements for NPT-threaded connections in these environments. It is sold individually and ships as a single piece.

Key Features

• 6061 aluminum alloy construction — corrosion-resistant and lightweight compared to steel alternatives
• Schedule 40 wall thickness — meets standard dimensional tolerances for NPT threaded pipe systems
• Threaded on both ends — ready for direct installation into fittings or couplings without additional machining
• OSHA-compliant — meets applicable occupational safety and health standards for piping components
• 4 inch nominal diameter x 4 inch length — a close nipple profile for compact inline connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 aluminum piping systems using standard NPT threaded connections in industrial, commercial, or mechanical applications.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line completely before removing any existing fitting or nipple. Use a compatible thread sealant or PTFE tape rated for aluminum and the conveyed media. Avoid over-torquing aluminum threads, as the material is softer than steel and susceptible to thread damage under excessive force.
