Merit Brass 8012-450 Aluminum Pipe Nipple Sch 40 6061

Product Description

The MERIT BRASS 8012-450 is a Schedule 40 aluminum pipe nipple machined from 6061-grade aluminum alloy, threaded on both ends for direct connection between pipe fittings, valves, or other threaded components. At 3/4 inch nominal diameter and 4.5 inches in length, this nipple bridges short gaps in threaded piping assemblies without additional fabrication. The 6061 alloy provides good corrosion resistance and structural strength at a reduced weight compared to steel or brass alternatives. Plumbers, pipefitters, and mechanical contractors install this type of nipple in low-pressure fluid, gas, and pneumatic piping systems where aluminum is the specified or preferred material.

This nipple is suited for residential and light commercial piping applications where a short, rigid threaded connection is required. Typical use cases include compressed air distribution, irrigation manifolds, and process piping where 6061 aluminum is compatible with the conveyed media. The Schedule 40 wall thickness conforms to standard pipe dimensions for 3/4 inch nominal pipe size, ensuring compatibility with standard NPT fittings and couplings.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and light weight
• Threaded on both ends for direct fitting-to-fitting or fitting-to-valve installation
• Schedule 40 wall thickness meets standard 3/4 inch NPS dimensional requirements
• 3/4 inch nominal diameter x 4.5 inch overall length for short-run connections
• Weighs 0.18 pounds — minimal added load in overhead or tight-clearance runs

Compatibility

Designed as a standard-dimension replacement or new-installation nipple for 3/4 inch NPT threaded piping systems using Schedule 40 aluminum pipe and fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or mechanical code requirements for the conveyed media. Verify that 6061 aluminum is chemically compatible with the fluid or gas in the system before installation. Apply an appropriate thread sealant or PTFE tape rated for the service conditions and hand-tighten before applying wrench torque to avoid cross-threading. Shut off and depressurize the system completely before removing or installing any threaded components.
