Merit Brass 8008-550 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8008-550 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy, designed for use in piping systems where corrosion resistance and light weight are priorities. It measures 1/2 inch nominal pipe size by 5.5 inches in length and is threaded on both ends for direct connection to standard NPT fittings and pipe. Weighing just 0.132 pounds, this nipple suits installations where steel would add unnecessary mass or where galvanic compatibility with aluminum components is required. Licensed plumbers and pipefitters install this type of fitting in low-pressure fluid and gas distribution systems.

This pipe nipple is suited for residential and light commercial plumbing, irrigation, compressed air, and industrial fluid transfer applications where 6061 aluminum construction is specified. The Schedule 40 wall thickness meets standard pressure ratings for the 1/2 inch nominal pipe size. Both ends carry NPT threads, allowing straightforward connection into existing threaded piping runs without additional adapters. Its corrosion resistance makes it a practical choice in environments where steel nipples are prone to rust or where weight reduction is a system requirement.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and light weight
• Schedule 40 wall thickness for standard pressure service
• Threaded on both ends with NPT threads for direct installation into threaded fittings
• 1/2 inch nominal pipe size by 5.5 inch length suits common close-nipple and extension applications
• Lightweight at 0.132 pounds, reducing load in overhead or weight-sensitive runs

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the service fluid before making up NPT connections. Do not overtighten, as aluminum threads are more susceptible to galling and damage than steel.
