Merit Brass 8064-450 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8064-450 is a Schedule 40 aluminum pipe nipple designed for use in piping systems that require lightweight, corrosion-resistant fittings. Manufactured from 6061 aluminum alloy, this nipple measures 4 inches in diameter and 4.5 inches in length with threads on both ends. It is suited for plumbing, industrial fluid transfer, and mechanical piping applications where standard steel fittings are not appropriate due to weight or corrosion concerns. Licensed plumbers and pipefitters install this type of fitting as part of threaded piping assemblies. The 6061 alloy grade provides a balance of machinability, weldability, and strength for general-purpose use.

This pipe nipple is used in residential and commercial piping systems where aluminum is specified for weight savings or chemical compatibility. Its Schedule 40 wall thickness conforms to standard dimensional tolerances for 4-inch nominal pipe, making it compatible with matching Schedule 40 threaded fittings and couplings. It is commonly installed in compressed air lines, low-pressure fluid systems, and light industrial process piping. The threaded-on-both-ends configuration allows direct connection between two threaded ports or fittings without additional machining.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and light weight
• Schedule 40 wall thickness meets standard dimensional tolerances for 4-inch nominal pipe
• Threaded on both ends for direct connection to matching fittings or ports
• Suitable for compressed air, low-pressure fluid, and light industrial piping applications
• Lightweight alternative to steel nipples in corrosion-sensitive environments

Compatibility

Designed as a standard-thread Schedule 40 replacement nipple for 4-inch nominal aluminum piping assemblies using NPT-threaded fittings and couplings.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply a thread sealant rated for use with aluminum to prevent galling and ensure a leak-free connection. Do not overtighten threaded aluminum fittings, as 6061 alloy threads can be damaged by excessive torque.
