Merit Brass 8024-400 Aluminum Pipe Nipple 1-1/2x4 in Sch 40

Product Description

The MERIT BRASS 8024-400 is a Schedule 40 aluminum pipe nipple measuring 1-1/2 inches in nominal diameter by 4 inches in length, threaded on both ends. Machined from 6061 aluminum, it provides a lightweight, corrosion-resistant connection for piping systems where steel would add unnecessary weight or react with the conveyed media. This nipple is used to join threaded pipe sections with a standard NPT interface. Licensed plumbers, pipefitters, and industrial maintenance technicians typically install this fitting in low-pressure fluid, air, or gas piping assemblies. The 6061 alloy grade offers solid machinability and structural integrity at Schedule 40 wall thickness.

This nipple suits residential and light commercial plumbing, compressed air distribution, irrigation headers, and industrial process lines where aluminum is the preferred material. It is appropriate for systems requiring a short close-to-medium length threaded extension between fittings, valves, or equipment ports. The 4-inch length makes it a common choice when a close nipple is too short and a longer nipple would interfere with adjacent components. Installers working on OSHA-regulated job sites will note the fitting meets OSHA standards as specified by the manufacturer.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 40 threaded aluminum piping systems using standard NPT connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or OSHA requirements for the specific piping system. Shut off and depressurize the line completely before removing or installing any threaded nipple. Apply a compatible thread sealant or PTFE tape rated for aluminum and the conveyed media — avoid sealants that can cause galvanic reactions. Do not use pipe wrenches directly on the aluminum threads without jaw protection, as excessive clamping force can deform the thread profile.
