Merit Brass 8020-300 Aluminum Pipe Nipple 1-1/4x3 in Sch 40

Product Description

The MERIT BRASS 8020-300 is a Schedule 40 aluminum pipe nipple machined from 6061 aluminum alloy, threaded on both ends for direct connection into standard pipe systems. It measures 1-1/4 inches nominal diameter by 3 inches in length and weighs 0.185 pounds. The 6061 alloy construction provides good corrosion resistance and strength-to-weight ratio in low-pressure fluid and air distribution lines. This nipple is suited for plumbing, HVAC, and light industrial piping applications where steel would add unnecessary weight or where mild corrosion resistance is needed. Licensed plumbers and pipefitters are the typical installers for this fitting class.

This nipple fits into Schedule 40 pipe systems using standard NPT thread connections. It is commonly installed in residential and light commercial piping runs carrying water, air, or compatible fluids where aluminum is an acceptable material. The 3-inch close-to-short length makes it practical for tight spacing between fittings, valves, or equipment connections. Both ends are threaded, allowing direct makeup with couplings, valves, or tees without additional adapters.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and reduced weight vs. steel
• Schedule 40 wall thickness for standard-pressure piping service
• Threaded on both ends for straightforward NPT makeup
• 1-1/4 inch nominal diameter suits common branch and main line sizes
• Meets OSHA standards per supplier specifications
• Lightweight at 0.185 pounds, easing handling in overhead or confined installations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 pipe systems using 1-1/4 inch NPT threaded connections where aluminum construction is specified.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter following applicable IPC or IFGC code requirements for the piping system in use. Shut off and depressurize the line before removing or installing any threaded fitting. Apply thread sealant or PTFE tape rated compatible with aluminum and the conveyed medium. Do not overtighten NPT connections into aluminum fittings, as the alloy is softer than steel and threads can be damaged by excessive torque.
