Merit Brass 8004-450 Aluminum Pipe Nipple Sch 40 6061

Product Description

The MERIT BRASS 8004-450 is a 6061 aluminum pipe nipple designed for use in threaded piping systems where lightweight, corrosion-resistant construction is required. Measuring 1/4 inch nominal pipe size at 4.5 inches in length, this nipple is threaded on both ends and manufactured to Schedule 40 wall thickness. It weighs 0.07 pounds, making it easy to handle during assembly. Plumbers, pipefitters, and mechanical contractors install this type of fitting in low-pressure fluid and gas distribution lines where aluminum's corrosion resistance offers an advantage over steel.

This nipple is suited for residential and commercial piping applications where 1/4-inch NPT fittings are specified. It is commonly used in compressed air systems, irrigation headers, instrumentation lines, and other fluid-handling assemblies that call for Schedule 40 aluminum pipe components. The 6061 alloy provides good machinability and thread integrity, making it a reliable choice for applications subject to vibration or repeated assembly cycles. It meets OSHA standards and carries the UNSPSC code 40173300.

Key Features

• 6061 aluminum construction offers corrosion resistance and a low weight of 0.07 pounds
• Schedule 40 wall thickness for standard-duty piping applications
• Threaded on both ends for direct connection to NPT fittings and pipe
• 1/4-inch nominal pipe size at 4.5 inches in length
• Meets OSHA standards (UNSPSC 40173300)

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch NPT threaded Schedule 40 aluminum piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and OSHA guidelines. Thread sealant or PTFE tape rated for use with aluminum fittings should be applied to the male threads before assembly. Avoid over-tightening, as aluminum threads are more susceptible to galling and deformation than steel. Depressurize and isolate the line before removing or installing any threaded fitting.
