Merit Brass 8064-800 Aluminum Pipe Nipple Sch 40 4x8 in

Product Description

The MERIT BRASS 8064-800 is a Schedule 40 aluminum pipe nipple sized at 4 inches nominal diameter by 8 inches in length. Machined from 6061 aluminum, it features threads on both ends for direct connection to fittings, valves, or other pipe sections. This nipple is designed for piping systems where corrosion resistance and light weight are priorities over ferrous alternatives. Plumbers, pipefitters, and industrial maintenance technicians install this type of nipple as a short, rigid connector between components in fluid-handling or gas-distribution assemblies. The 6061 alloy provides solid machinability and resistance to a broad range of media.

This pipe nipple is suited for residential and commercial piping installations where aluminum Schedule 40 fittings are specified. Common applications include compressed air lines, irrigation headers, low-pressure fluid transfer, and industrial process piping. It is compatible with standard NPT-threaded fittings sized for 4-inch pipe. Installations that call out OSHA compliance requirements are supported by this fitting's listed standards. The 8-inch body length makes it appropriate for close-coupled connections requiring a defined standoff distance between two threaded ports.

Key Features

• 6061 aluminum construction for corrosion resistance and reduced weight compared to steel
• Schedule 40 wall thickness for standard-duty pressure applications
• Threaded on both ends for quick, tool-ready installation into NPT fittings
• OSHA-listed standard for use in compliant workplace piping systems
• 4-inch nominal diameter x 8-inch length covers common close-coupled spacing needs

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch NPT-threaded aluminum piping systems built to Schedule 40 specifications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and OSHA piping regulations. Depressurize and isolate the line section before removing any existing fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Avoid over-tightening, as aluminum threads are more susceptible to galling than steel.
