Merit Brass 8020-450 Aluminum Pipe Nipple Sch 40 6061

Product Description

The MERIT BRASS 8020-450 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy, measuring 1-1/4 inches nominal diameter by 4-1/2 inches in length. It is threaded on both ends to NPT standards, allowing direct connection between fittings, valves, or equipment in piping assemblies. At 0.25 pounds, it is lightweight without sacrificing structural integrity. Plumbers, pipefitters, and mechanical contractors install this nipple in low-pressure fluid and gas distribution lines where corrosion resistance and weight savings are priorities over ferrous pipe.

This nipple is suited for residential and light commercial plumbing, compressed air, irrigation, and industrial fluid transfer applications where 6061 aluminum is an acceptable material specification. The Schedule 40 wall thickness meets standard pressure ratings for these service types. Its threaded-both-ends configuration makes it a straightforward close or extension nipple in any standard NPT piping layout, compatible with aluminum, brass, and other NPT-threaded components.

Key Features

• 6061 aluminum alloy construction offers good corrosion resistance and light weight
• Schedule 40 wall thickness meets standard pressure requirements for typical fluid and gas service
• Threaded on both ends for direct NPT fitting-to-fitting installation
• 1-1/4 inch nominal diameter suits common mid-size piping runs
• Lightweight at 0.25 pounds, reducing load in overhead or multi-nipple assemblies

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 40 NPT piping systems requiring a 1-1/4 inch nominal aluminum pipe nipple with threaded-both-ends configuration.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC guidelines for the intended service. Shut off and depressurize the line before disassembling existing connections. Apply an appropriate thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Avoid over-torquing aluminum threads, as the alloy is softer than steel and susceptible to thread damage under excessive force.
