Merit Brass 8012-400 Aluminum Pipe Nipple Sch 40

Product Description

The MERIT BRASS 8012-400 is a 6061 aluminum pipe nipple designed for threaded piping assemblies in industrial and commercial plumbing, pneumatic, and fluid-handling systems. Machined from 6061-series aluminum alloy, this nipple measures 3/4 inch nominal diameter by 4 inches in length and conforms to Schedule 40 wall thickness. Both ends carry full NPT threads, allowing direct connection between two threaded fittings or female-threaded ports. Licensed plumbers and pipe fitters install this type of component in low-corrosion environments where aluminum's light weight and resistance to rust are preferred over steel or galvanized options.

This nipple is suited for residential and light commercial piping runs where 3/4 inch threaded connections are required. Common applications include compressed air distribution, water supply laterals, and process fluid lines where aluminum is compatible with the medium being conveyed. Its Schedule 40 wall thickness supports standard working pressures typical of threaded pipe assemblies in these service conditions. The 4-inch length makes it appropriate for close-coupled connections and offset runs where a standard hex nipple would be too short.

Key Features

• 6061 aluminum alloy construction for corrosion resistance and reduced weight compared to steel
• Schedule 40 wall thickness for standard-pressure service
• Threaded on both ends for direct connection between fittings or ported components
• 3/4 inch nominal diameter fits standard 3/4 inch NPT threaded fittings and valves
• OSHA-referenced standards compliance
• Weighs 0.124 pounds for easy handling in overhead or tight-access installations

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or qualified pipe fitter familiar with threaded pipe assembly practices. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly to ensure a leak-free joint. Hand-tighten first, then use a pipe wrench to achieve proper engagement without over-torquing, which can crack aluminum fittings. Verify that aluminum is chemically compatible with the fluid or gas being conveyed before placing the nipple in service.
