Merit Brass 8020-550 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8020-550 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy, measuring 1-1/4 inches in diameter and 5-1/2 inches in length. It is threaded on both ends to standard NPT specifications, allowing direct connection to female-threaded fittings, valves, and manifolds without additional adapters. Weighing 0.325 pounds, this nipple is suited for plumbing, HVAC, and industrial piping systems where corrosion resistance and light weight are priorities. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers of this type of fitting.

This pipe nipple is used in residential and commercial plumbing and mechanical systems where aluminum piping is specified for corrosion resistance in wet or chemically aggressive environments. Schedule 40 wall thickness makes it appropriate for moderate-pressure service in fluid and gas distribution lines. It can serve as a close connector between threaded components in compressed air, water supply, and process piping assemblies. Its 1-1/4 inch nominal size fits standard pipe trains in both new construction and retrofit applications.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and reduced system weight
• Threaded on both ends for straightforward connection to standard NPT female fittings
• Schedule 40 wall thickness for moderate-pressure service
• 1-1/4 inch nominal diameter x 5-1/2 inch length for versatile span applications
• Lightweight at 0.325 pounds, reducing load on piping supports

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical code requirements. Depressurize and drain the affected line section before removing or installing any threaded fitting. Apply thread sealant or PTFE tape rated for the conveyed medium to all threaded connections before assembly. Do not over-torque aluminum fittings, as the alloy is more susceptible to thread damage than steel.
